When I open my Windows Live email the whole screen turns an odd color, the normal menu of standard items disappear in the tool bar, each message is highlighted a pea green color and reading who sent the message is extremely hard to read.  Then when I close the email program and it returns to the desktop which in turn is a completely different color fuzzy look and nothing resembles the original desktop, after 30 seconds or so it changes back to the original background.  Any suggestions would be greatly appreciated.  BTW, this computer has Windows7.
