From the description, it seems to me like the image caching is not
being properly managed (ie not refreshed) when moving it from display
to display. Try setting NSImage's cache mode to never cache. Or, use a
IKImageView (part of the Image Kit palette bundle in IB) and see if
the problem follows it.
I'm very interested to hear what you find!
