I am using mstsc.exe version 6.0 (Remote Desktop non-Metro version) from an XP machine and cannot get Windows 8 in a Xen VM snapping to work. I can drag a metro app window to the left or right, but it doesn't stick, it just bounces back to full screen. The snap bars do not appear.
The client PC has two monitors, each with a resolution of 1280x1024. While mstsc.exe 6.0 does have an option to use both monitors simultaneously in normal settings, I am launching it with spanning enabled:
So the effective resolution in the session is 2560x1024.
Is there a trick to getting this to work over RDP?
