Alt+F5 got ya down?

An issue I had to solve tonight for someone: on many modern Windows computers, Alt+F5 can't be used in applications. Instead, the screen goes blank and comes back (or, in the case of LCDs, may do nothing).

The culprit? ATI's video drivers. They're apparently trapping the Alt+F5 key combination for something. This is not well-documented -- as far as I've been able to found in a brief search, ATI doesn't mention this functionality anywhere.

The solution is to open the Displays control panel, switch to the "ATI Options" tab, and uncheck the "Enable ATI taskbar application icon" option. Once you apply the new settings, Alt+F5 will no longer be trapped by ATI's software and will be available to all your applications.

Alt+F5 causes ATI to attempt to "switch amongst displays" in case you have multiple displays one one computer.

I've been buggered by this for months. I actually humbled myself to map perfectly good alt+F5 shortcuts in applications to other key combinations. Couldn't somehow guess it could be turned off from that menu. Million thanks, everything's happiness and glee now.
