DECterm chokes after doing graphics?

[Rice Don D]

I've been installing NCAR graphics on a DS5000/Ultrix 4.0.  While running
through the test plots using the vt340 graphcap, the decterm froze...not
during the graphic display, but while printing compiler messages.  I found
that "Clear Communications" (not "Reset Terminal") fixed it, with output
picking up where it left off.  But it froze up again sometime later, after
viewing more plots.  With a fresh decterm, I have no problems until I have
viewed several plots.  Since the decterm chokes some time after the graphics
are done, and it doesn't seem to be very deterministic, I suspect the decterm
rather than the plotting program.

Has anyone else done a lot of graphics in the decterm window, vt340 style, and
experienced (or failed to experience) such problems?

Thanks,
