Keyboard controls Issue: control stuck in one direction

[repuken2]

Hello everybody,

i installed ppsspp 9.8 on my arcade machine, i have a j-pac, so my control is an usb keyboard.

Whenever a play a game , after a while the controls get stucked in one direction, only directionals D-PAD (up,down,left, right), action buttons seems fine (X, circle, etc). Tried 9.7 and 9.6 but same problem exists. Tried metal slug XX, Street Fighter Alpha 3 MAX, puzzle bobble, Ultimate Ghouls n' Ghosts to see if it was game specific but same thing.

All other emulators and pc games controls work fine (Mame, Desmume, CPS3, model2, model3, zsnes, etc) so it seems ppsspp related.

Did anybody had the same issue?
Any suggestion?

Thanks in advance,
cheerz.

Forgot to mention i'm using windows xp 64 bit (Retros 64 wich is a modified version of xp 64, slightly modified for arcade cabinet use).
Trying it on my desktop machine wich is windows 7 64 bit ultimate there's no issue. I think it's direct x related.

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!!!.
