remote desktop open multiple times in nested windows

[Casper Bergenhammer]

weird problem here..

system:
  win2k pro

Installation:
  realvnc4 server+view package.
  server an viewer installed on the same machine
  default configuration

problem description
  when I connect to the localhost vnc server the viewer
  opens the desktop, but within that vnc viewer desktop
  a new instance is opened, and within that a new instance
  and so it continues until the system is brought to a halt
  and all I can do is reboot the hard way.

Anyone with an idea?
If more information is needed, let me know.

thanks.
Casper
