hmm... this problem has been tracked down to an incompatibility
in the behavior of the (rather old) VRPN client code in VMD and
the newer server code in VRPN-ICMS. so using a VMD binary
linked against a newer VRPN library resolved that for real.

that is unusual and unexpected. i have no idea how this would
correlate to the connection issues, but thanks for letting us know.

since you spent already some time on this, would you mind
doing one more test? and use the contributed alpha test
binaries of VMD that include the new VRPN client code?
those should allow you to work with the newer nvidia drivers.
thanks,
axel.
