I have a Dell Precision M6500 with and ATI video card. This annoying behavior just start a few hours ago. I press Ctrl-1 and my active windows moves from monitor 2 to monitor 1. Or vice-versa. I've looked at the windows (Windows 7) display settings and at the ATI software and cannot find anyway to turn this off. This fuction is messing up my program that uses Ctrl+1/Ctrl+2 to move to bookmarks within the program.
