It sounds like you have a ClipRect problem.  When QD scales a picture, it
also scales the ClipRect.  If I am not mistaken, this causes problems a lot
of the time, since the ClipRect is often set to -32768,-32768,32767,32767.

Try setting the ClipRect to something reasonable like the portRect.

This little "bug" drives me crazy, even when I know to expect it.
