I've been running OSVnc on one machine for a couple of weeks to monitor some projects.

Yesterday I connected to it using CotVnc and noticed that I couldn't seem to input anywhere on the screen; i.e., clicking did nothing anywhere I tried.

I killed the VNC server process on the remote machine and restarted it via a shell, but still I can't input in CotVnc.

Has anyone seen this behavior?  I can post hardware and software details if needed.
