Quick Look won't close
For the last week or so, I find that occasionally, I can't get the quick look preview window to close. I hit space to preview a folder full of images, and when I was done viewing all of them, hitting space does not dismiss the quick look window. I tried clicking the x in the top left corner, tried setting it to full screen and clicking close, but that didn't work. The only solution is to log out and log in again. I couldn't find any associated processes in Activity Monitor.
