Hi! Comparing the time of blitting from one context to another with different operating systems and same context sizes results in _boring_slow_ blitting on Windows (MinGW32). I'm using GNU Pascal on both systems. I just create a background context, draw a line in it and blit it into the foreground context. Doing it 10 times (selecting background, drawing, blitting to foreground) takes about one minute. With Linux, it is incredible fast. Is there a faster way with MinGW32? -- Eike Lange
