I upgraded to version 4.1 and now I can't connect to my Ubuntu machine using vino. VNC viewer allows me to input the password, but it gives me a pop-up saying "Connection to server lost". I can connect to my Windows machine fine, so it may be some small change that is causing it to fail on the Linux machine. I'm going to roll back to version 4.0 for the time being. Thanks again detlef.
