You >don't mention it but are you rendering through the window's RastPort >(clipped) or the Screen's RastPort (unclipped) ? Sorry, forgot that. I'm was using the window's rastport. Now I'm using the screens Rastport ( since I'm doing my own clipping - I read somewhere the screen's rastport is quicker because it doesn't do any clipping ... is this true? ) ps. anyone have any particular things they would like to see in a shell ( I'm toying with the idea of writing one ). Email me any thoughts.
