Unexplained VNC behavior

After a lot of experimentation and searching of the mailing lists I'm still no closer to resolving this problem. Can anyone help?
I'm invoking vncserver v4.0 on a SunOS(v5.8) machine using the following command:
vncserver -depth 8 -geometry 1280x1024 -cc 3 -alwaysshared
This VNC session invokes dtwm. I'm viewing the vnc session on a PC(Win2000 pro) using vncviewer v4.0.
There is something definitely going wrong when I open some pull down menus (particular the ones that control closing/resizing etc). Once this occurs, then weird things happen including:
- mouse clicks have no effect.
- mouse pointer shape/direction from right-left to left-right. It does not return back to normal (right-left).
- I can enter text into existing xterm, but it won't appear until I move the mouse.
It appears that the vncserver keeps on running but the mouse and keyboard commands are not getting through.
I've tried using different machines locally and remotely. I've tried various vnc session window managers. I've tried invoking dtwm using "dtwm", "dtsession" and "xsession". I got the person on the remote end to replicate the same setup and the same problems as I'm seeing. All without success.
Does anyone know what I'm doing wrong or what is going wrong? Is there any fix that I have missed?
Thanks in advance.
