I'd like to piggyback onto your thread to say that my Ventrilo push-to-talk button (left CTRL button) does not work when FFXIV is my active window. It seems that with the last patch, all keys that have a special function outside of the game have been disabled while the game is active.

I haven't found any option to change it back to the way it used to be.

Because I rely on voice chat for raiding, I don't know what to do about this. I sincerely hope it's something that we can circumvent.
