I get a quarter inch blue circle on my screen and it goes around and around sometimes for 5 minutes before it stops. I I try and click on another part of a program it will lighten the screen but does not lose the program It has does this hundreds of time and calling AOL has not helped. I redownloaded the AOL program and that also did not help. The only way to get rid of it is to get out of program and start over. Sometimes it does not bother me at all and then it does it 5 or 10 times in a row.

Did you totally uninstall and then reinstall AOL?

Is it only in AOL?

Have you tried any type of malware program?
