VS6 - When you hover over the definition field in the definition bar so that the tooltip "Definition" pops up, and the tooltip covers part of the edit field, the edit field is repainted all white-on-white when the tooltip disappears. By double clicking into the edit field you can see that it still contains text because the selection is then repainted correctly.
I remember that I've seen (and reported) this effect in VS.Net. In my case the whole field was repainted white-on-white, except the part that was beneath the tooltip. Is this the case for with also?
