Can you close that box with the ESC key?
Don't you see an OK button?
The ESC key does close the box. I can see the OK button but it doesn't do anything. I noticed this weekend that this problem only seems to occur on a 32 bits Windows XP or Windows 7 and not on 64 bits versions of Windows

It was indeed caused by an custom Add-on. I notified the developer of this add-on. Thanks very much.
