Well, that's quite a problem. The program seems to be dying without running any code (that I control) at all, so without some kind of error or way to reproduce the behavior, there's only so much I can do about it. I'll look into compiling for Windows with Qt 4, but I don't know if that'll help. Also, I fixed the bug that was sometimes causing exported ROMs to crash/reset while trying to load the intro. Will put up a new build later.
