Does it still happen if you remove the visual effect?

I noodled about looking at the text appearing and disappearing as it should, when the standalone crashed.  I ran it on a physical machine, and it didn’t crash under Win 7 or Vista, but I did notice the memory allocation embiggening with most, but not all, appearances of the tool tip - between .2 & .7 MB a time.  The memory was never released when left alone or navigated to another stack.
