Re: A DirectInput problem

Nope, works correctly for me (though I tested this on April 2006 SDK -
don't ask, that's what I had handy :) ). I'd say you should try with a
different keyboard, perhaps you have a ghosting problem in the
hardware.

On another note, I've never used DirectInput for keyboard or
mouse. IME, I've had more robust results and a simpler solution by
intercepting the keyboard/mouse events (WH_GETMESSAGE, WH_CALLWNDPROC
- both need to be checked at the same time) directly for keypresses
and GetCursorPos() for mouse position.

HTH,
Alen
