Ctrl+Alt+C Shortcut Problem in Indesign CS3

I cannot use the ctrl+alt+c shortcut in IdCS3. The alt key works with all other shortcuts. I believe this is caused by ATI's catalyst control center which uses the same shortcut to open it's window but I disabled the hotkeys in catalyst and even changed that hotkey to one besides ctrl+alt+c and I can still not get the shortcut to work in Id.

This happened to me about a year ago and I can't remember how I fixed it.

Thanks in advance for any help.
