Thoren <pthoren@cs.uml.edu> Reply-To: "sdl@libsdl.org" <sdl@libsdl.org> To: "sdl@libsdl.org" <sdl@libsdl.org> 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; ~ Philip D.S. Thoren
