Artifacts in view

We sometimes get artifacts in the GoView display area after we close a window or menu that was hiding part of the diagram. It is as if the view is not repainted properly. Any suggestions to get around this issue would be greatly appreciated.

I don’t recall ever seeing that. Do you see remnants of the window that was closed? Or do you use GoDiagram objects that don’t belong where you see them? Is there any way to show us how to reproduce this problem?
