I don't think the GtkAda example testgtk/create_gc.adb works as it should either. I can compile testgtk.adb without errors and get the gc-demo to look like this: http://wb592924.bahnhofbredband.se/gc/gc.png Should it look like that? I guess not. What could be wrong? Any idéa? I use gnat 3.15p and GtkAda 2.2.0 on Windows 98 SE. Regards Markus
