Starting yesterday, I've had this little window pop-up on my desktop. It won't go away until I click on it and then just pops-up again. I looked at Task Manager, and I don't see any processes that might be associated with it. I've run a scan, and it's not malware, and searching Google returns no results (which I find incredible). Has anyone else seen this before and can shed some light on it? I am running Win7 x64.
