In writing my full screen INIT (which the net provided NO help for) I have noticed some odd behavior when I draw. Basically, I am creating a window with a rect the same size as screenbits.bounds, and then doing a UnionRgn between the visrgn of my window and the WindowMgr port. After I have the window initialized I clear it to black (to blank the entire screen) and then do a simple animation routine. If I draw in the upper left corner, I get parts of the twin Appleshare arrows left on the screen after I erase my drawing. Why is this? Is there any way to stop this behavior? Has anyone else noticed this behavior. Any help you can provide would be appreciated. Please e-mail responses to me directly if possible. Scott Storkel Macintosh Software Development Rice Univeristy
