Ian, I recollect vaguely a problem in OS X 10.0 (and 10.0.1) where drawing
horizontal and vertical lines in XOR mode would lead to memory big-bang. If
you check the mail archives there is more detail about that.
The workaround is to make sure that your rect is not zero-sided - if either
width or height of it are 0 don't draw it, draw a line instead. An even
better workaround, perhaps, might be to use MRJ drag-drop APIs instead of
cooking up your own. (Even though I'm not positive they go back all the way
