Subject: [SDL] BUG in src/video/windx5/SDL_dx5events.c
I tracked down a bug that crashed my program on Windows *all* the
time.
FILE: src/video/windx5/SDL_dx5events.c
FUNCTION: handle_mouse
BUG:
SDL_PublicSurface is being dereferenced when it is NULL.
I added the following to the very begining of handle_mouse
and it solved my crashing problems:
if (SDL_PublicSurface == NULL) return;
