[McIDAS #FTB-213912]: Image Display Issue, MCIDASx2007c on AIX

Hi Martha,

- was v2007c the first instance of the 2007 distribution that you tried,
  or did you install v2007 and then upgrade?

- what are the specific symptoms of the display failure?

OK, very interesting indeed.

Just to be clear: you are saying that you were running the tests I
suggest in the Unidata McIDAS-X Users Guide?  And, you were able to
run the tests once using the build with the Vendor compilers (xlf/xlc)
but an EXIT out of your McIDAS session followed immediately with
tests in a new McIDAS session showed failures?

Now I am totally confused.  Your comment 'and McIDAS just returns to
its command prompt' makes me think that you are not talking about
running the tests within a McIDAS session.

So, you can not display data from sessions running on your AIX box or
from sessions running on other boxes pointing to your AIX box?

The load on the box should make no difference in data display outside
of the speed of the display.

- from a McIDAS session on the AIX box, can you correctly display imagery
  from another system outside of your shop?

Here is the test to run:

<login as 'mcidas' on your AIX box>
-- start a McIDAS v2007 session
-- point to an ADDE server on some other machine and see if you can
   correctly display imagery:


Your display should look like the GIF that I have attached to this email.
