Gilbert,

OK, I logged in with X tunneled, and found your problem.  When you
reloaded the ~mcidas/.mcidasrc file was deleted.  When you started
the first McIDAS session, a new .mcidasrc file was created, but it
had the default settings for your session.  One of these defaults
was the number and size of frames which was 4 frames of 480x640.
The MCGUI expects there to be at least 17 frames, so any plotting
that was to occur in frames greater than what you had would fail.
Display of single images is defaulted to frame 10 which did not
exist, so the display failed.  Plotting of loops worked -- sort of --
since the loops will display starting in frame 1.  You were getting
loops of 4 frames since that was all the frames you had.

So, I started McIDAS using the GUI startup:

mcidas -config

and set the number of frames to 17.  While at it, I set the size of
frames to be 600x800.  I then remembered to save the settings 
through a radiobutton at the bottom of the startup GUI.

I then started a McIDAS/MCGUI session and displayed GINIWEST satellite
imagery with no problems.

Hi Tom,

re: compress is contained in ncompress-4.2.4-34 rpm.  Here is how I found
this out on our machine that had a _full_ Fedora install:

Tom,

re: trying to load images in MCGUI running with only 4 frames
>YES!!!!

>Yep, it works fine now! DUH! Boy, do I feel stupid...I should have never
