The only games I've had sticky key problems with so far are Alien Vs. Predator and Rogue Spear. Oddly enough Rainbow6 runs fine.
The problem occurs using a Microsoft wheel mouse USB, and with a Logitech wheel mouse PS/2. I've tried Microsoft's latest USB internet keyboard, and the Microsoft PS/2 Internet keyboard. Any combination of these still suffers from sticky keys in the above games.
