I saw a number of messages about this in the archives, but no one ever came
up with a solution. I hope the debug logs I have will help.
Briefly, I am connecting to a target machine that is running Windows
98. The problem is that shortly after connect, the VNC session will hang,
and after disconnecting any new sessions have only a blank black
screen. The system needs to have the VNC client closed and re-opened to
re-connect to the machine. The problem happens in both service and
application mode. The problem seems to happen more frequently if I use the
JAVA viewer instead of the Windows viewer, though both will eventually
cause the problem. When I turned on debugging in the registry, the problem
became much harder to duplicate (it took me a week to get it to happen
again.) Here is what I think is the relevant snip of the log:
