Subject: Re: [SDL] Hardware buttons on pocket pc
I found it! :)
It has to do with the UNICODE translation code, in SDL_dibevents.c, in the
'#ifdef NO_GETKEYBOARDSTATE' block in DIB_HandleMessage(). The error
handling is a little... aggressive. If it can't translate from unicode, it
wipes out the virtual keycode.
