When I am using the keyboard in my game, sometimes, each key whose code is higher than 128 stops working. If it was pressed it remains pressed (In the keyboardBuffer[256] that I pass to GetDeviceState, of course). If it was released, it remains released even if I press the key. Does anybody have an idea on what''s the origin of this UGLY problem? Someone had or have the same problem? Thanks in advance!

Perhaps your keys are getting stuck? Tried another keyboard?
