The one that shows up when you mouse over someone/thing. Is there a way to hide or move it?
Tiptac should do what you want.
TipTac will allow you to move it wherever you want on the screen.
Interface > Help > Uncheck "Enhanced Tooltips"
MoveAnything should do what you want. You can move the tooltip off your screen, to a more desirable location, or hide it entirely. It can do the same for pretty much every piece of your UI as well. So helpful.
