I've never encountered problems hiding and showing objects. The behavior you describe can be attributed to overwriting bounds of user memory. When I was setting the form title to a string longer than the original length, I've also seen weird stuff like this happen. Can you isolate you code to only perform Hiding/Showing? If you can and the problem goes away, your bug may lie elsewhere.
