Using Rumba on my desktop trying to connect to a demo application running on Enterprise Server installed locally;  it only worked once and now it keeps showing "Unowned" at the bottom of the Rumba window. A connection is impossible from the host to the server.

Resolution: Reboot the machine as somehow there is a connection problem with the host to the server which has nothing to do with Rumba. The error 'Unowned' basically means it cannot find the server for unexplained reasons. Rebooting and all works fine again.
