Spotlight leaves folder on desktop

[Noctilux.95]

I have a Mac Pro (4,1) with 10.7.3
Whenever I do a search with Spotlight and scroll down the list of found folders, the corresponding window stays permanently on the desktop until I restart the computer.
Anyone else have this problem?

Maybe you should supply a screen shot.
