Fixed bug #695 Nomad 2009-02-08 10:34:43 PST The 2nd init is good. The problem is in "SDL_dibevents.c" in DIB_CreateWindow() in SVN: { char *windowid = SDL_getenv("SDL_WINDOWID"); SDL_RegisterApp(NULL, 0, 0); ... using of data to which windowid is points problem: SDL_RegisterApp() may call SDL_getenv() and windowid will point to some wrong string solve: char *windowid; SDL_RegisterApp(NULL, 0, 0); windowid = SDL_getenv("SDL_WINDOWID");
