Windows 7 Problem closing or resizing open windows


New Member
I have a problem closing , resizing , minimizing and maximizing open windows in Windows 7.
The windows controls in the right side upper corner used to modify the behavior of the windows open do not function and The only way to close a window is to do it from the Task Bar.

I have a G31 based Mother board and I am using the latest graphics drivers and Aero do work for me .
I am using Windows build 7000.
