I have not experienced this problem, but my use of a DEC is limited
(I typically run on either Solaris, Solarisx86, AIX, or Linux).  I
do have a site that recently loaded on an Alpha, and I have not
heard about any problems from him.

The problem you describe sounds like some portion of memory is getting
stepped on.  Have you ascertained whether or not it makes a difference
which frames are used for the display?

>thanks,

Sorry I can't be of more help.  Unfortunately, I am on travel until
Thursday, so I can't even try to duplicate your problem.

Tom,

It does not matter what frames i use. Typically i have a LB of 1 15 which
gets updated every 15 minutes with new GOES imagery. Ultimately each frame
gets wiped out! I do not have such a problem on my AIX box. I am thinking it
may have something to do with the graphics cards on these 2 Alphas cause my
older Alphas (600 series) which different cards do not have the same
problem.
