HTML button issues

Hi, when I click the HTML mode button on the editor on a new install, and on the online demo I get the following errors and the HTML mode editor is not initialised. Screenshot attached of popup.

Firefox error console:

Error: illegal character
Source File:
Line: 1, Column: 6
Source Code:

Error: tinyMCEPopup is not defined
Source File:
Line: 1

Any suggestions? I assume it isn't an issue with my install as the same happens on the online demo.

Many thanks,

Well it looks like you're getting a GIF image delivered instead of the JavaScript file. I'd say the problem lies on your end. Maybe it's a Firefox extension that messes things up?
Did you try another browser too? Which version of Firefox are you using?

Thanks for the reply Banal, I'm using FF 3.5.5.

I've also tried it in IE8, Safari and Chrome with the same outcome. I only have add-ons for FF (firebug, web dev toolbar).

IE8 error msg below:

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; GTB6; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; InfoPath.2; .NET CLR 3.5.30729; .NET CLR 3.0.30729)

Thanks for your help

That's really strange. Demo Site works here (FF 3.5.5 Mac OS X)
Maybe also check from another computer (if possible)?

That's made me think...

I just paused my Kaspersky security suite protection and it works fine!

Very strange and a little annoying as I don't really want to have to deactivate my AV to use the HTML mode. I'll have to do some digging into the settings.

Thanks for taking the time to help

In case anyone else is using Kaspersky Internet Security and runs into this issue, I've tracked down a solution on the TinyMCE support forum:
