Javascript failing on IE works if debugger is open

So, I am in a conundrum with my JS failing after a certain amount of time through the menu navigation. Since it works with the console debugger open, I assumed it was a console.log error, but I have removed those functions.
If you open up this page, http://behrent.com/test/Industry.html, in internet explorer, then use either your arrow keys or the menu headers to scroll many times right or left in a row it will break. It currently works in Chrome and FF.
It's almost as though the js crashes or something.
Any ideas on what might be occurring? My JS doesn't have any console.log.
On another page using same css and js, but different html it is also producing scary behavior. http://www.behrent.com/test/Services.html. Basically if you go to that site you can navigate through them if you go slowly, but if you go very quick it will then break in the same fashion as the first page.
Just hope I don't have to move to another layout.

Figured it out. IE was expecting background images in the various sections, but I didn't indicate that any existed. IE got confused because it was expecting them as I indicated, but they didn't exist in the css, so it just broke.
Calling not existent sections with js makes things break. The more you know...

ContentVeil.js and Forced Synchronous Layout Issue

I have a php page that hangs for 3-10 seconds after the page loads, you can't even scroll up or down, or close the tab when this happens. (the chrome loading gif still loops tho) Happens in Chrome and IE.

Shows ContentVeil.js repeating over and over. I think it is client side(?), I did a grepWIN to search for ContentVeil, with no luck, and it doesn't show up in Chrome Network tab.
Chrome Profile: Second image, from above link.
I think this shows the issue at the anonymous function from meta-boxes.min.js, ln 1.
meta-boxes.min.js: http://pastebin.com/yqtJyqB1
Unfortunately line one is a function that encapsulates the whole script. I don't know js very well, I tried to just remove each function one by one but that just created more errors.
Any ideas on how I could find the source of the problem would be much appreciated.

It's part of the Evernote web clipping extension, and it's hooks DOM events, causing massive slowdowns if you are doing large amount of dom changes.

Internet Explorer 10 hiding buttons or preventing JavaScript from working?

I'm not normally in a need to ask basic or vague JavaScript questions on SO, so pardon me if there is little details here - I'm not sure how to get more.
In the online user manual I'm maintaining, I'm adding custom buttons on each page to get a direct link to the current page (otherwise grabbing the URL just brings you to the home screen), as well as a few extra features. These buttons are added using Javascript, or rather they are already hidden in the HTML, are updated after an AJAX call and then displayed.
It has taken me a lot of work to get these working, in Firefox, Chrome, IE6, 7, 8, 9, I'm sure you know how these things go.
Now comes IE10 with yet another really weird behavior that I want to bang my head on the wall for. If you visit http://help.objectiflune.com/en/knowledgebase/ you will see those buttons on the right inside the main frame. They're grey and blue, top of the page.
So this first "welcome" page is fine, it works great, no issue. However, if you navigate to any sub page using the TOC on the left (such as Error Codes -> PlanetPress Design -> PlanetPress Design Error PXXXX), the buttons all disappear.
I've also noticed that if you get the URL for the page itself (inside the frame, again) and you open it in another tab, it first does not show them, but then refreshing the page makes the buttons appear.
I've tried using the F12 developper console, but it requires refreshing the page to show the console so I can`t use it in those new tabs. As for using within the whole frame system, it doesn't seem to be showing me any errors, nothing weird.
Again I'm sorry if this is an "it's not working" with no further technical details, but... there are none I know how to give.
UPDATE: For the specific code, please turn to http://help.objectiflune.com/common/scripts/olCommon.js , and look at the function starting at line 207 (function buildMenu()). this is the function that retrieves the information and displays the appropriate menus, such as $("#guidebuttons").show();

In ObjectifLune.css, #buttoncontainer has display: none. Navigating through the F12 window, the display of that object is none:
I would guess that somewhere in your JS, you're setting the display to block, but there's something wrong with that code in IE.

"Error calling method on NPObject" on first page load

since a few days there seems to be a problem with a audio player script (flash + javascript) on one of our pages that NEVER occured before and I changed absolutely nothing in the code (it has worked for a few years now) that could cause this issue.
We bought the audio player script a few years ago, and again, until a few days ago, it worked perfectly.
The error also behaves very strange. Let me explain...:
The page is www.imatunes.de . You can see these small audio players on each article there.
Feel free to check out the code, got nothing to hide there.
My coworkers told me, that suddenly nothing happened if they clicked on the "Play" buttons. Normally, the script should start the flash player, which plays an audio file.
Now comes the "somehow" strange part:
My coworkers are all using Google Chrome. When they open the page in Chrome and click on a "Play" button, the JavaScript console throws the following error:
"Error on calling method on NPObject".
Googling that error says it has to do something with actionscript, cross-domain policies and such. But the error will get stranger...:
I'm using Firefox, and there it works FLAWLESS. But it also works on MY Google Chrome flawless, so it's very hard to debug (that's why I'm here to ask).
My coworkers also tried it on their home PCs, also running Google Chrome and such, and it also doesn't work there.
Now comes the "very" strange part:
When they get this error and reload the page via the browser controls (F5 or the reload button), it still won't work.
But if they browse around the page or just click on the logo in the header (which basically takes them to the home page again), the script magically works.
And on every other page except for the home page, it will work on first try.
As I said before, this started a few days ago - before that, everything worked just fine. And I really didn't change anything in the code.
So regarding the fact that it works after they browse around the page and return to the home page, it somehow seems like some sort of caching error.
I really don't know how I could debug this, or what to do.
Thank your for every possible help in advance!

Javascript disappearing on refresh IE

I'm having some issues with Javascript content on Internet Explorer, specifically, a page will appear to be empty on refresh but if you open the page from a link it will display correctly.
Site: ABuenPaso.cr
User: sof
Pass: stackoverflow
To go to the page with issues click on 'Registro' on the top menu.
The calendar uses the Fullcalendar plugin
The reviews are Ajax calls to a php file
General page usage instructions*
When the page first loads you'll be able to see a calendar with events and a weekly/monthly activity review. If you reload the page in IE, however, neither will show. Click on the 'Registro' button on the top menu again and they should display properly.
Also, in IE the form won't autocomplete in its entirety when clicking an event; the extra text areas that display when selecting 'Otros' in the 'Entrenamiento' and 'Tipo' drop-down menus won't show either.
Chrome and FF 3.6 are both working without a hitch (I've gotten some error reports from people using FF 3.5 but it worked fine for me). I've tried using the debugger that comes with IE8 but the only error reported is caused by an undefined variable used by a poll plugin that is used elsewhere.
The fact that the calendar/reviews work fine in Chrome/FF and will load on first entry at IE makes me think its not strictly a JS code problem. Other than that I have no clue what could be the problem and I've been stumped for a couple of days now.
Any help would be appreciated.
Thanks,
Tom
General page usage instructions:
You can reach the page with problems by clicking on 'Registro' on the top menu bar and logging in with the information provided above.
The 'Aceptar' button will create a new event on the selected day, the only required values are 'Entrenamiento' and 'Tipo'.
The 'Borrar actividad' button will delete a selected event, it requires the 'Entrenamiento' to match the events value (this will set itself on Chrome/FF).

Turns out IE wasn't executing the onload that loaded/executed the scripts. Moving this to a $(document).ready solved the problem.
