Are you sure you’re using the correct coordinate conversions? Based on what Graham said, there are actually 3 coordinate systems involved — the content view coordinates, the content (i.e. non-frame) coordinates, and the frame coordinates. Officially AFAIK there are only 2 coordinates systems (frame and content). If you’re accidentally mixing coordinate systems, perhaps you don’t need to adjust the calculations, but just use a different conversion?
