  Has anyone out there ever had any problems with the reliablity of
the VPL Dataglove boxes before?  We have found that ours crash after
being on for more than twenty minutes or so (they just freeze up).
The problem appears to be heat related.  We have installed fans on
the black boxes and this improves the run time but does not solve it
altogether.  (Hmm...maybe a bit of a timing problem?).

The serial numbers on our boxes are p167 and p168 (about four years
old).  We are running the boxes in oneshot mode.  We did try sending
one of the boxes back to VPL and they claimed nothing was wrong with
it.  Has anyone else run into this problem?

Thanks for any info,
