Okay here is a simple project file. I tested it in 4 browsers. It does nothing in latest FF and Chrome. In Opera it only does half the actions and in IE it actually works.
I updated to catalyst 11.11 and I'm running Windows 7 64bit.
I found the problem. I'm running two 6850's in crossfire mode. I had a strange feeling it had something to do with that. Once I disabled crossfire mode it works as intended.
Disabling crossfire only fixes it in FF. It is still Broken in Chrome and Opera.
C2 sh*ts itself if you have it open when you enable/disable crossfire. I have to close it from task manager.
