We have 2 users with windows 7 laptops. They connect to a terminal server via RDP. When it connects it starts full screen but after around 30mins to 1hr the screen resizes and they are forced to use up and down / left and right scroll bars to navigate around it. I have tried turning of the "prevent windows from being automatically arranged when moved to the edge of the screen" setting in the ease of use section but this does not seem to have made a difference. Any suggestions..
