Connection lost when user logs in windows 7

[paolodurante94]

I can connect to the server if all user accounts are disconnected but as soon as a user logs in I get disconnected. If I try to reconnect I get disconnected immediately after the authentication.
Server and client have both the same ultravnc version: 1.2.1.0. I use ultravnc every day with a lot of different pc and it always worked. Can someone help me?
Thank you

You connect with vnc and logon .... then the connection breaks
OR
You are connected with vnc and logged on as user, then another user logon using RDP.

Please also try the 1.2.11rc3 ( downloadable via forum), we don't debug older versions, we are already
working on the next one.
