Keymapped attacks locks up all windows

Running into a major problem, that i've never had any run in with before.

EVERY time i SHIFT+ALT+M(Default enable / disable Key Map hotkey)..And use an attack, The 1st attack goes off, But the 2nd attack / broadcast attack, hard locks all the WoW windows - And requires me to CTRL+SHIFT+ESC(Task Manager) and and go over to Processes and manually end the process, as closing the windows isn't possible.

Anyone ever ran into this problem? Or have had it happen and been able to solve it?

If it helps at all, I just reformatted to 64 bit Windows 7 Ultimate / Copied WoW over to the External Hard Drive and then onto the new computer's desktop. I even rebooted the computer, applying updates, etc, still crashes upon hitting that first attack that is key mapped to broadcast to all the toons.

All necessary drivers are installed i think, ATI Cataclyst / DirectX(Installed with ISBoxer bundle)..Everything else is working fine(PC Component wise). Seems to only be happening when i enable key maps and use an ability that broadcasts to the other toons, As without key maps enabled, The windows don't crash.

If anyone could help, it would be appreciated - As i'm unable to run my group(s) until i get this fixed.

Thanks!

Solved via ISBoxer chat. The problem was an infinite loop caused by a mapped key calling a mapped key calling a mapped
key calling a mapped key calling a mapped key calling a mapped key calling a mapped key...

I think you all get it.
