Thanks for the link Shawn. I guess I'll have to live with that.

"Note: For performance reasons, Cocoa does not enforce clipping among
sibling views or guarantee correct invalidation and drawing behavior
when sibling views overlap. If you want a view to be drawn in front of
another view, you should make the front view a subview (or descendant)
of the rear view."
In fact IB and ibtool warns about this when you compile a XIB.
If you are using layer backed views I think this restriction goes away
since layers have a more formal Z ordering requirement. I am not sure
if restricting to 10.5 alone is enough to deal with this (don't think
it is).
You normally deal with this by nesting views... your text view would
be a subview of the image view or by doing custom rendering.
