I am a civil engineer and I have downloaded Windows Live Messenger on my pc and I am suffering with a weird problem which is that whenever I open the messanger I hve two black spots one on top and seconed one at the bottom I am confused with it because I don’t know whether I have downloaded a wrong messenger or it is due to graphic card which is not enbuild in my pc. So if anyone had ths problem before can contact and tell me what should I do to make it right.pls help
