This helps to overcome the problem in Armored Fist 3 and in Droplitz. 
The problem still occurs in Star Wolves 3, maybe less frequently. A sure way to
reproduce the problem in SW3 is to alt-tab out of the game, then alt-tab back
to it. This didn't happen before the patch.

This didn't change anything.

btw. I have an AMD Athlon 64 x2 4200+ cpu, running @2.2 GHz.
