Keyboard controls Issue: control stuck in one direction

[repuken2]

I answer myself:
problem was caused by having mapped Left Alt key , it seems io thread get's crazy handling alt wich also toggles window menu.
Funny thing is that it doesn't happen on windows 7. Anyway i remapped that key to another more friendly and now i can play psp games on my arcade cab flawlessly now.

Excellent emulator, cheerz & thanks a lot to the authors for their hard work!!!.
