Running VNC server and Remote destop XP simultaneously - not working

	I've just done a little test with Win2003.

	Inside a TS session, I run VNC as an application in another display number.  Then I resize Remote Desktop screen window to the minimum (I don't know if this is useful, but I realise that I can't minimize the RDT window).  In this way, I could use VNC client to this session.

	I'm having 1024x768 at about 128 kbps and I could say the responsiveness is acceptable.

Thanks, but another display number didn't help.

Now I take it as feature :-((
Wez @ RealVNC Ltd. says: This is a known limitation of current releases.
