why is MIDI scripter dropping events after 20x loops in MainStage 3

my drum riff script seems to work up until the riff is repeated (i think around) 20 times. then some notes like snare... start to dissappear. if i hit the global stop and play again it works. also if i reload the script it doesn't help which makes me think... but come up with the road to nowhere. any ideas?
The problem starts at beat position 640 (20x 32 beats per loop).

The scripter plugin was loaded on a drum kit software instrument channel and works great for the most part.
I've traced each beat with another scripter plugin and all the notes have been logged, so i assume they've all been sent properly. All the notes should be there but they just can't be heard.
I've tried all kinds of things, i'm stuck!

Font Resizer Javascript Not Working In IE8 and IE7

I am trying to put a font-resizer on my company' website since a lot of our customers are the elderly and they have no idea about Ctrl + "+".
Here are the codes we have. The resizer works fine under FF, Chrome, and IE9. But not in IE8 and IE7. I omit the create cookies/read cookies parts here.
function createCookie(name,value,days) {.....codes for create cookies......}
function changeFont(incfont) {
try{
var p = document.getElementsByClassName('resizable');
for(n=0; n<p.length; n++) {
if(p[n].style.fontSize) {
var size = parseInt(p[n].style.fontSize.replace("px", ""));
} else {
var size = parseInt(window.getComputedStyle(p[n],null).getPropertyValue('font-size').replace("px", ""));
}
p[n].style.fontSize = size+ incfont + 'px';
}
p = document.getElementsByTagName('p');
for(n=0; n<p.length; n++) {
if(p[n].style.fontSize) {
var size = parseInt(p[n].style.fontSize.replace("px", ""));
} else {
var size = parseInt(window.getComputedStyle(p[n],null).getPropertyValue('font-size').replace("px", ""));
}
p[n].style.fontSize = size+ incfont + 'px';
}
} catch(err) {}
}
function readCookie(name) { ....code for read cookies ....}
function increaseFontSize() {
var inc=0;
try {
var x = readCookie('textsize')
if (x && x!=0) {
x = parseInt(x);
inc = x;
}
} catch (e) {}
if (inc<3) {
inc++;
changeFont(1);
createCookie('textsize',inc,1);
}
}
function decreaseFontSize() {
var inc=0;
try {
var x = readCookie('textsize')
if (x && x!=0) {
x = parseInt(x);
inc = x;
}
} catch (e) {}
if (inc>0) {
inc--;
changeFont(-1);
createCookie('textsize',inc,1);
}
}
Thanks in advance!

Your solution seems overcomplex to me, I will suggest you a different approach, set a base text size for the page body, and then for the rest elements set font-sizes in percentage, that way when you want to resize the text of all the site you just have to do:
$("body").css("font-size", newFontSize);

getComputedStyle doesn't work for IE prior to 9.
See:
https://developer.mozilla.org/en-US/docs/DOM/window.getComputedStyle
A fix might be available here : http://snipplr.com/view/13523/
I didn't test it,
Good luck !

I'm trying to stop snow script and clear the page after x seconds

How can I make the snow clear after a certain time. I've tried using variables and the calling a timeout which switches on to false and stops the makesnow() function but that doesn't seem to clear the page at all.
<script language="javascript">

else return 800;
}
function makeDiv(objName,parentDiv,w,h,content,x,y,overfl,positionType)
{
// positionType could be 'absolute' or 'relative'

}
var snowC=0;
var x = new Array();
var y = new Array();
var speed = new Array();
var t=0;
var cC = new Array();
var ra = new Array();
function makeSnow() {
x[snowC] = Math.round(Math.random()*(browserBredde()-60));
y[snowC] = 10;
makeDiv("snow"+snowC,"body",32,32,'<img src="http://i693.photobucket.com/albums/vv296/KIBBLESGRAMMY/CAT/Orange-tabby-cat-icon.gif">');

}
function moveSnow() {
var r = Math.round(Math.random()*100);
if (r>70 && snowC<20) makeSnow();
for (t=0;t<snowC;t++) {
y[t]+=speed[t];move("snow"+t,x[t],y[t]);
if (y[t]>browserHoyde()-50) {y[t] = 10;x[t] = Math.round(Math.random()*(browserBredde()-60));}
cC[t]+=0.01;
x[t]+=Math.cos(cC[t]*ra[t]);
}
setTimeout('moveSnow()',20);
}
moveSnow();
</script>

makeSnow just adds the snowflakes. Stopping that, as you say, does not clear anything. moveSnow handles the animation, and calls itself at a timeout. If instead of setting a timeout for the next moveSnow each time, you set it up to run in an interval just once, you would have an easier time stopping it.
window.snowAnimation = window.setInterval(moveSnow, 20);
If you add a css class to your snow flakes, it would be easier to target them for deletion.
oDiv.className = 'snowflake';
Then your clear function could look something like:
function clearSnow() {
window.clearTimeout(window.snowAnimation);
var flakes = document.getElementsByTagName('snowflake');
for(var i = 0, l = flakes.length; i < l; i++) {
document.body.removeChild(flakes[i]);
}
}

Timeout doesnt help, it helps you only to stop creating new snowdivs, however if you see makeDiv is the one which creates new divs on to the body, if you clear / display:none the divs which got created on makeDiv i hope it will clear all the divs on the screen.

You need to remove the divs that were created. It might be easier if you give them all some sort of class, like ".snowflake" as you create them (in makeDiv), then start removing them from the dom.

You will have to clear the elements created after the time you wanna stop snow falling.
Following code snippet will help you to clear the elements
if(count < 500){
setTimeout('moveSnow()',20);
}else{
var i = 0;
var elem = document.getElementById('snow'+i);
do{
elem.parentNode.removeChild(elem);
elem = document.getElementById('snow'+ ++i);
}while(elem != null)
}
count++;
you have to create a global variable count.

Javascript only works in IE Quirks, 7 and Chrome and Firefox. Doesn't work in IE 8 or 9 Standards

My code makes a number of divisions appear to orbit around an invisible horizontal axis on a plane. How it works: it fires a mouseevent listener onMouseDown, and captures the X of the user's cursor relative to the window. onMouseUp is simulated by a setTimeout function that is called 90 milliseconds later, it does the same and then subtracts the two values to determine the distance and direction to spin.
My question is: Why does it work correctly in FF, Chrome, and IE Quirks and IE 7 Standards, but not IE 8 Standards or IE 9 Standards?
IE8: the model breaks down and the divisons float away outside the containing boundary division. IE9: No response from the JS whatsoever.
The following contains the entire javascript on the page, which can be found # http://electrifiedpulse.com/360.html :

</script>
I don't know what may or may not be relevant to you, so I included the entire script. If you want you could ignore the longest function,
iScroll()

#RyanStortz. Try to register events in this maner:
var isMouseCaptured=false;
function i_boundary_mousedown(ev) {
isMouseCaptured=true;
iScrollListen("Down");
}
function doc_mousemove(ev) {
if(isMouseCaptured) {
ev=ev||event;
myX=ev.clientX;
myY=ev.clientY;
}
}
function doc_mouseup(ev) {
if(isMouseCaptured) {
isMouseCaptured=false;
ev=ev||event;
myX=ev.clientX;
myY=ev.clientY;
}
}
var i_boundaryObj=document.getElementById('I_BOUNDARY');
if(window.addEventListener) {
i_boundaryObj.addEventListener('mousedown',i_boundary_mousedown,false);
document.addEventListener('mousemove',doc_mousemove,false);
document.addEventListener('mouseup',doc_mouseup,false)
}
else if(window.attachEvent) {
i_boundaryObj.attachEvent('onmousedown',i_boundary_mousedown)
document.attachEvent('onmousemove',doc_mousemove);
document.attachEvent('onmouseup',doc_mouseup)
}
else ;//
Add for DIV with class "I_BOUNDARY" id attribute "I_BOUNDARY" and remove onmousedown attribute.

Internet Explorer loop bug when preloading images

I have created a JavaScript application that requires all images to be preloaded first. Everything works fine in Firefox but in Internet Explorer my loop skips the count at 19 and goes to 21. Has anyone come across this problem before and what causes it?
You can copy and paste the script below for test purposes.
var preLoad = function () {
var docImages = ["http://www.sanatural.co.za/media/images/map/rsa_prov.gif", "http://www.sanatural.co.za/media/images/map/loading.gif", "http://www.sanatural.co.za/media/images/map/loading2.gif", "http://www.sanatural.co.za/media/images/map/ec_land.gif", "http://www.sanatural.co.za/media/images/map/ec_roll.gif", "http://www.sanatural.co.za/media/images/map/ec_state.gif", "http://www.sanatural.co.za/media/images/map/fs_land.gif", "http://www.sanatural.co.za/media/images/map/fs_roll.gif", "http://www.sanatural.co.za/media/images/map/fs_state.gif", "http://www.sanatural.co.za/media/images/map/gt_land.gif", "http://www.sanatural.co.za/media/images/map/gt_roll.gif", "http://www.sanatural.co.za/media/images/map/gt_state.gif", "http://www.sanatural.co.za/media/images/map/kzn_land.gif", "http://www.sanatural.co.za/media/images/map/kzn_roll.gif", "http://www.sanatural.co.za/media/images/map/kzn_state.gif", "http://www.sanatural.co.za/media/images/map/lp_land.gif", "http://www.sanatural.co.za/media/images/map/lp_roll.gif", "http://www.sanatural.co.za/media/images/map/lp_state.gif", "http://www.sanatural.co.za/media/images/map/mp_land.gif", "http://www.sanatural.co.za/media/images/map/mp_roll.gif", "mp_state.gif", "http://www.sanatural.co.za/media/images/map/nc_land.gif", "http://www.sanatural.co.za/media/images/map/nc_roll.gif", "http://www.sanatural.co.za/media/images/map/nc_state.gif", "http://www.sanatural.co.za/media/images/map/nw_land.gif", "http://www.sanatural.co.za/media/images/map/nw_roll.gif", "http://www.sanatural.co.za/media/images/map/nw_state.gif", "http://www.sanatural.co.za/media/images/map/wc_land.gif", "http://www.sanatural.co.za/media/images/map/wc_roll.gif", "http://www.sanatural.co.za/media/images/map/wc_state.gif"],
imageFolder = [],
loaded = [],
loadedCounter = 0;
this.loadImgs = function () {
for (var i = 0; i < docImages.length; i++) {
imageFolder[i] = new Image();
imageFolder[i].src = docImages[i];
loaded[i] = false;
}
intervalId = setInterval(loadedCheck, 10); //
};
function loadedCheck() {
if (loadedCounter == imageFolder.length) { // all images have been preloaded
clearInterval(intervalId);
alert('All images have been preloaded!');
return;
}
for (var i = 0; i < imageFolder.length; i++) {
if (loaded[i] === false && imageFolder[i].complete) {
loaded[i] = true;
loadedCounter++;
alert(i); // (work fine in FF but i.e goes from 19 to 21 )
}
}
}
};
var preloadObject = new preLoad();
preloadObject.loadImgs();

The reason for this is that the item on index 20 is "mp_state.gif" - its missing the complete url.
Because of this the image isn't loaded, the .complete property is set to false, and so the loop skips this item.
