Window Size on Windows 7

When I create a remote desktop connection in Windows 7 the windows is created maximise and docked to the top left corner of the screen, if I move the window then the window shrinks to a smaller size (note: this doesn't happen on Windows XP).

Someone reported a similar problem here: http://forum.devolutions.net/topic290-windows-7--rdm-minimizerestore-strange-behaviour.aspx#post1418 and their solution was:
"I have the solution for this, in my RDP file:
desktopwidth:i:1280
desktopheight:i:1024
session bpp:i:16
winposstr:s:0,3,0,0,1380,1124

If the desktopwith and heght are less than the two last entries in wniposstr, the issue isn't there. So I have made my rdp files by adding 100 to each. Problem solved.

In you program, you have to set winposstr accordingly."

I have tried setting winposstr in a hand crafted rdp file and that does solve the problem. Please could this be added to temporary rdp file that RDM generates.

Thanks, Neil
