Problem with copiesOnScroll of NSClipView

Hello,

I would like to use copiesOnScroll of NSClipView to speed up scrolling of my custom document View, but after a change in scaling of the ClipView copiesOnScroll doesn't work on horizontal scrolling any longer. For vertical scrolling copiesOnScroll still forces the document view to redraw only the exposed portions but for horizontal scrolling the document view is always forces to draw itself completely within the documentVisibleRect of the ClipView.

Any hints what I'm doing wrong?

A demo project (Xcode 2.2) to demonstrate this behavior is available here.

Greetings

   Dan
