Yes, you are correct - I was just drawing the frame of the accessory view as a sanity check, and it worked as expected.
It turns out that the problem is with the 10.7+ overlay scroller drawing. If I return NO from +isCompatibleWithOverlayScrollers then it all works as expected. If I return YES, then my subview is not drawn. The subview is present as a subview of the scroll view and in the right place, but not shown.
Any ideas?
Regards
Gideon
