I am working with Unreal Tournament 3 editor and whenever I try the In Editor Game window to test my edits, I lose all keyboard and mouse control. However, I can hit the tab key to get the command line.

If I use "cntrl-alt-del" to close the In Editor Game window, I get mouse and keyboard control back and everything seems to function normally.

Anyone know what might have happened?

I have Win XP, all the latest updates for Unreal, and the Titan Pack.

oh yah, PS: It does it no matter what file I open to work on.
