My version of Windows is Win-7- Enterprise.
When updating to version 6.1.7601.65536 I see that the screen where the map and game units should appear appears in "gray" (first img).
I also see that the program does not manage the screen well since hiding the RIGHT SIDE INFORMATION PANEL, does not restore (repaint) the map screen correctly.
(first img)The same thing happens with the message window (second img),
which when minimized leaves a trace on the map screen (third img). In order to see the "clean but gray"
map screen, I have to minimize the C:MO and then maximize it again....
