James, thank for the reply. The task causing the problem is
vncviewer.exe, hogging between 50 and 70% of CPU constantly, causing
overheating of my windows notebook. When I connect to a windows box,
there is no problem.
I thought it could be related to the polling etc on the linux box, and
was wondering if these setting can be altered for a standard fedora 3
install as a test.
Has knowone else had these sorts of problems? I have seen it in other
threads here, but it was blammed on a buggy earlier version.
Thanks.

Nicholas,
Check the task manager on your notebook to see what is causing the CPU
usage. I'd bet it's kernel CPU usage (i.e. the CPU usage bar will mostly
be red), and that it's caused by some sort of problem with your operating
system drivers.
VNC 4.0 and VNC 3.3.7 are completely different codebases, so a CPU-hogging
bug in one is unlikely to also exist in the other.
More importantly, if an application using the CPU can cause your laptop to
overheat then there is something seriously wrong with its internal
temperature control, indicating either a power management driver problem or
a hardware fault.

Subject: CPU overloading in WinVNC connecting to Linux box
My CPU is maxing out causing overheating on my notebook when
connecting
to a Linux Fedora Core 3 box. I use this application to connect to
windows machines with no issues. I have downloaded and tested the
viewers for v4.0 and 3.3.7 and the result is the same - maximum CPU
usage on my windows client machine.
Can anyone advise a fix for this? Can I configure the
vncserver on the
linux box to minimise this, and if so what configuration/file is used?
Thanks.
Nicholas
