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;
