I am using pc anywhere 11.0 on a xp pro computer and tring to connect to windows 7 pro computer using 12.5. When I connect to the computer I sometimes get checker boards on the screen and the connection is real slow. My screen will not show all of the contents( they will be blank or blacked out), does anyone know how to fix this? If I installed 12.5 on the xp pro machine, would that correct issue?
