Magnifier

I have had this problem a few times before, but it seems to correct its self after a while,but it is staying now. I run Windows XP and my magnifier comes up. I don't know what I did to make it come up. I have everything I know to do but I cannot get it to go off. I Googled it and found lots of folks are having this problem, but I found no solution. Please tell me how I can turn this off. When I go to the accessories click on the magifier,it brings up aother larger magifier. I can click it off and it goes off, but this smaller one stays. Please Help. Thanks in advance.

Never mind, guys, I rebooted and the magifier hasn't come back yet. But I did find a solution that should have worked and may work for anyone with this problem. Press the Windows + U keys. It didn't work for me because the message that appeared says that my magifier was "not running" so I couldn't delete it. Hope this helps someone else. Thanks guys for being there.
