Carsten,
  There's no need to send duplicate emails, it just clogs everyone's
inboxes and irritates people that aren't involved in the topic at hand.
I have four copies of your message now... So, please be patient.

I haven't had a chance to look at this in detail, but that looks
more or less like I might expect. I'll have to get back to you on
this as I have some work to finish by a deadline this week. Try
using the printing Tool in VMD and see if you get stable values or if
they vary wildly as you say the display does when using VMD against
the same VRPN server.
