> Hi Ryan, > I checked the list you linked to, but did not see any reference to whether > the Win32 window centering bug was fixed... Has that been addressed at all? > I refer to the bug where, unless one has globally set the > SDL_WINDOW_CENTERED variable in the OS, only the 1st window that is created > will be centered. Subsequent calls to SetVideoMode will create a window tha t > shares the same upper-left corner location. I'm working on that now, thanks for reporting it. What I'm doing is if the width and height are the same, I'm leaving the window position alone, but if they're different they will respect the positioning environment variables.
