How do I make the Spotlight menu hint bubble go away in OS X Lion?

Question

In Mac OS X Lion when you bring up the Spotlight menu and start typing something, a large-ish hint bubble will pop up to give more info about the selected result. That's all well and good except that it occasionally gets stuck and I can't make it go away.

Is there a way to get rid of this window without resorting to logging out?

Alternatively, is there a way to just get rid of those popups altogether?

Answer 1

Kill the process named "Quick Look UI Helper" using the Activity Monitor application. Frustrating little bug, huh?

Answer 2

Or type this in Terminal:

killall QuickLookUIHelper

For what's it worth, yes, this bug unfortunately still persists in Mac OS X 10.7.3 - just run into it.
