There is a tiny window that I am unable to identify or close. It is big enough for me to move but I can't seem to stretch it to make it bigger, I can't close it. It does not appear to be any of the items listed as Applications in the Task Manager.
Is there any sort of program that allows me to identify a process by clicking on the window of the application?
I really want to know what this is. If I log out it goes away but something I am doing is causing it to re-appear.
Any ideas how best to troubleshoot it?
