I had installed Windows Vista on my machine. I'm using Windows Live Messenger 2009 in a compatibility mode on Windows Vista. Now the problem is that whenever i try to use Windows Live Messenger on my system, my contacts gets sign in automatically at the bottom right of the screen. In order to resolve the issue, i had reinstalled my Windows Live Messenger, but it didn't resolve my issue. So, can any body tell me that how do i resolve Windows Live Messenger compatibility mode issue on Windows Vista? Does any body knows about it? Kindly help me out to get rid of the above issue. Thanks.
