Hi Todd,
     The new beta release (1.0.4) I just made is working on my new
Red Hat (5.4) with kernel 2.6.18-164.11.1.el5 #1 SMP Wed Jan 6 13:26:04
EST 2010 x86_64 x86_64 x86_64 GNU/Linux.
     Please give a try and let us know if it works for you.

Hi Todd:
   I checked your file 100218_12:11:29 with the test version on RTDC3.
The file itself seems to have no problems to load into MIRIAD with
the smalod in the beta release.
   I noticed that you are using the very new Redhat release (5.4) with
a newly updated kernel. The symptom from your report appears to be
very similar to that Ram Rao reported. I had a problem to repeat
this bug with my old desktop (Pentium 4 with FC9). I just got a new
Linux box and Pat is working on loading the updated Redhat enterprise
(5.4). She is struggling with Dell since our order has not been updated
in their system. We will let you know as soon as we fix the problem.
