This is what I wanted to know, since I don't have VFP7 to try. I agree, the problem should be isolated to the actual cause, I just haven't tested it too much. I read article, tried to reproduce, that's all. I tested with and without set status bar, _VFP.AutoYield and wait window and see memory increase in all tests. I didn't try other properties than ToolTipText (I suppose, StatusBarText or comment would behave the same way, but need to test)
