My Win 7 computer started doing something I have never seen before. I leave it on all the time and it goes to sleep after a while. When I wake it up sometimes the various windows only fill about 1/4 of the screen. They are in the upper left corner as if they are in the reduced mode. The indicator in the upper right corner shows two boxes indicating that the screen is maximized (but it is not). When I click on the boxes to "reduce" the size of the screen it gets just a little smaller. When I click on it again it maximizes properly to fill the monitor. Needless to say this is a real pain since I keep at least five or six boxes open all the time and I have to go thru this on each one. Any ideas?.
