Keypress event catches only en_us clicks, however another class catches en/russian keypresses !!! why?
-
Hello guys,
I am in a difficult situation .. An error and I don't know where. I have 2 classes, one catches keypresses in any layout (english/german/french/russian ... etc) (this is the keygrabber class) and one catches keypresses only in the en layout (this is the practise class) although both are mostly similar.
Can any body figure where is the difference between them?

Why does keygrabber accept all keypresses in all layouts, but practise not?
