Window Closing 'ALT' button hep

[Ze-Jamz]

Guys i dont know whats happened here but im using a Saitek3 Eclipse keyboard and for some reason i cant close windows in game which use the 'ALT' button?

Ive tested the button with some 'keyboard tester' programs and its recognized in windows..

Is there a command for that 'ALT' action in options that i may have deleted by accident?

I now have 3 windows open in the middle of my screen i cant close

EDIT..Had to get rid of them bu editing the config file... what a PITA
