VNC servers growing stale, slow

[Stephen Fromm]

James,

Thanks for the reply.

I'll try your suggestion, but another question:  right now, the system timer 
is broken on our Solaris system.  (It goes back one hour every hour, so it's 
stuck between say 1:10 pm and 2:10 pm on 2006-09-11.)  The VNC log says
" VNCSConnST:  Time has gone backwards - resetting idle timeout"

Could that cause the problem?

Cheers.
