Hi Gerry-

> Institution: AATLT Texas A&M University
> Package Version: 2.3b2 build date:2007-07-31 23:58 UTC
> Operating System: Linux
> Hardware Information: Java: home: /home/idv/IDV_2.3/jre version: 1.5.0_11 
> j3d:1.5.1 fcs (build6)
> Inquiry: An error has occurred:
> Probe moved

I haven't been able to reproduce this, but I put in a possible fix.  It
seems like it's a race condition with the probe trying to sample before it
has data to sample.
