Have you tried using DxWnd?
...
Providing you are in 32 bit colour depth.....
I'll have a word with Cisco, he may be able to come up with a way to edit the window size via the launcher, and the registry values edited after the size has been changed.....
This does not work, Dxwnd just ignores the X and Y size settings. If i disable stretching the client crashes. The launcher could do that directly but there is a problem, i have to know all the border sizes from xp,vista,7 including there styling/theme modes (classical view, low performance vista/7 view, high performance)
EDIT: OK, figured out you can read these widths directly from windows: SM_CXBORDER and SM_CYBORDER.
EDIT2: Wrote a test code, the maths are now correct but the window cant be resized via windows natives (user32.dll) or the build in function...
