DHTML Window interferring with iframe

[Whee]

Hi!
I used your script DHTML Window (http://www.dynamicdrive.com/dynamici...ndow/index.htm) to embed tinychat on top of a mibbit chat.

http://www.wasabite.com/index2.html

However, for some reason, when I use DHTML Window, some people, but not all, cannot see the mibbit chat in firefox. I have no idea what can cause this and I cannot reproduce the bug myself.

Help needed.

Thank you very much.


Edit :
I also had to enclose the mibbit iframe into a div container because moving the window was a nightmare (slow and VERY jerky).
