GARP 2.1 locks X-display on Sol 7 Sparc

We have had problems with GARP freezing and locking up the X-display
on our Sun UltraSparc running Sol 7 (latest MU).  It seems to happen
about once a week mainly when trying to load profiler or
satellite images.  I have to telnet into the machine and kill it.
I have not had a chance to install GARP 2.1 on our Intel machine
yet.  This did not happen with 2.0.  

Thanks,
Robert Mullenax
