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.
