Hello Rick,  

Yep! I started vncserver as my login name, graeme.

Nope. Started it as my mortal self.

Maybe I'm wrong, but I don't think so, because if I start vncviewer on
the same machine I started vncserver the password is read no problem. It
is only when I start vncviewer on the 'other' machine.

No, both machines have a 1024x768 screen size, the machine running the
server and the machine running the viewer. When I log in from the
machine running the viewer the window, labeled 'TightVNC: Graeme's X
Desktop etc...', has scroll bars which interfere with the application.
The 'actual' window size appears to be 1024x768, the same physical size
as the screen, but the scroll bars take up display area causing the
problem.

If I start vncviewer with the command 'vncviewer -geometry 800x600x0x0
-via barney barney:1' to stick the window in the top right corner, or
wherever, it still comes up bigger than the screen's real estate with
the scroll bars. If I then click on the full screen icon (trc) the
scroll bars disappear but the window is slightly larger than the
machine's screen resolution/size (1024x768). The docs for X mention the
the -geometry option but I wasn't able to get it to work when I start an
Xterm for a particular size, simply puts up the usage screen saying the
-geometry option was not valid. Perhaps the problem with vncviewer is
linked with the X problem, I don't know.

Thanks Rick, sorry to be a nuisance but I would like to sort it if I
can.
