Intel XDK More than one cordova.js script?

I'm trying to build an app using Intel XDK, and I'm running into problems. Things were going well at first, but this morning I was prompted to update XDK, and now my app isn't working.
My login page works fine, and the resulting page with links to various pages in the app work. But when I click a link, the page loads, but is blank, and then I get a JS alert saying:
"It appears you have more than one script tag for cordova.js. There can only be one!"
I found the tag and commented it out to see what would happen, and the only thing that changed was I didn't get the alert. The page is still blank. The only coding I've done was the login script on the index page, so I don't know why it broke. I tried restarting the program, and even recreating the app, and it's doing the same thing. Any ideas why?

There were a variety of changes to the Emulate tab with the new version. I get the impression you're using the Emulate tab. I recommend that you test with the Debug tab on a real device, it will give more accurate results.

After some experimenting, I've come to realize that the problem was I was using List View buttons to navigate, and I was navigating to a different page altogether. That was causing my problem. I just combined all of the pages into one, and it works fine, now.

Linking between pages and loading JavaScript using jQuery Mobile

I'm working on my first jQuery Mobile site, which is a (prototype for) a Location Based Game in Brisbane, Australia: www.jsjensen.dk/soleil/
My question is based on viewing from a mobile device, but a desktop device have very similar problems. I have tested with Chrome and Safari on iPhone, iPad, and Mac. Same problem everywhere.
I think it's related to how jQuery Mobile loads and displays pages, but I'm not using multiple pages in one HTML document, but have multiple HTML document.
If you go to the website above and then click "QUESTS" in the menu, followed by "Stairway to Knowledge" you will end on /soleil/quest01.html (desktop) and /soleil/#/soleil/quest01.html. That "#/soleil" really confuses me!
In this first try the JavaScript for handling answers in the text input is not loaded. That means nothing happens when you press "Unlock".
Now, if you reload on desktop or edit the address on iOS to /soleil/quest01.html (which is the actual and real file) it will reload the page with the right JavaScript loaded and initialized.
Now I'm able to go back (pressing "QUESTS" in the menu) and then go to another page (e.g. "Citadel of Fun") with the same problem: the JavaScript not loading. If I go back to the other one ("Stairway to Knowledge") the JavaScript is, however, still loaded and working just fine.
So what happens here? I'm pretty sure my linking/coding is correct, but it's just a basic understanding of jQuery Mobile that I'm missing. Can I change something to make this work? It could really be awesome!

So, I found a way to fix it, but not really a solution to the original problem.
I've added rel="external" to the tags pointing to the pages where I had problems. In this way it will not use the AJAX system to load these pages, but do it in a regular way. This solved my problem, but now I can't make any fancy transitions.

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.

"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!

Mootools Javascript slideshow freezes after browsing website

Hi I have been using Rokstories, a mootools javascript slideshow in Joomla, I am having a very odd problem with Rokstories in IE . I have uploaded a temp copy to my server to show everyone.
If you click on my link in IE , the page loads and Rokstories works as normal, sliding from left to right every few seconds......click one of the other menu links, then go back to the home page and Rokstories does something very odd, the dots move along to say that it is going between slides, but the actual slide stays put and dont move.
If you clear your cache and reload the page it works fine again until you browse to another menu item and come back, then the problem starts again.
I have tested this with IE8 and get the problem, I have also tried it in Chrome & Firefox and done see a problem.

The first thing I notice (apart from the Google Maps API key alert) is that IE throws an error:
Line: 989
Error: 'Cufon' is undefined
Looking on Chrome/Safari/Firefox all throw up 404 on cufon-yui.js & /plugins/system/Cufon/key4font_400-key4font_700-key4font_italic_400-key4font_600.font.js
Our experience has been the IE will sometimes fail when JS files aren't in cache when it expects them to be. You might want to fix those first.
