I was using AOL Instant Messenger. I don't know what I did but now the program's window is always maximized, and it won't let me restore the window to its normal small size.
Is there something I can do to be able to change the program's window, besides having to re-install the program? This has happened to me with other programs also.
Note: this is not the type of problem I can fix by double clicking the program's title window or the middle button located at the top right.
