First of all thanks a lot for doing that much work porting GTK to windows. I can't count how many apps I've used myself on windows-pcs which were able to run because of your work. > If one would ask specific question like "I draw 100000 line segments > with separate gdk_draw_line() calls, and it's too slow on Win32" one > might get better help. I installed gimp on some win-xp computers in the company I work for (sempron 1,6ghz or so) and also saw some kind of slow behaviour. These are very much the issues I have on linux but more "visible". Its the UI, menus, window resizing, layout changes or repaint-events sent to the window because its content was invalidated. I can't say wether its really slow or just feels so, maybe the graphic card driver had an influence (nvidia gf4 mx4000) or some other circumstances were not optimal. I simply never did care that much simply because I don't use/like this planform. Its just hard to know whats going wrong, especially if someone is no gtk insider. lg Clemens _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
