All,

I have forwarded the following problem to Quarterdeck technical support,
and want to hear from people experiencing the same problem, and if they
have found any causes/solutions:

- It is almost impossible, using DV/X telnet or PC/TCP tn/rlogin, to run an
  X client back on DV/X desktop -- usually crashes all of DV/X, requiring a
  cold restart

- The above problem of DV/X crashing hard is not limited to the case of
  using a telnet or rlogin session to start an X client -- just about any
  kind of network activity (opening X windows on DV/X desktop with DV/X rsh
  or from another X window, opening DOS windows on a remote system with DV/X
  run or from the remote system itself using remsh/rsh, etc.) can cause
  disaster!!!

PC/TCP 2.1 is working very well on this system, as all of its utilities
never crash the machine or do the unexpected.  Also, two different network
interfaces, the Novell NE2000 16-bit and 3COM 3C503 Etherlink II 8-bit,
have been tested with equal results (using Release 10.x Crynwyr packet
drivers), to weed out potential hardware timing problems with the network
interface.  Nor have we had any problems of the kind with the workstation
console X servers themselves or X displays, when trying the same operation.

The setup of the system is *not* exotic -- here are the DOS startup files
(stripped down to their bare minimum, yet still exhibiting the above
problem), from which you will notice nothing whatsoever is high-loaded,
Stealth RAM is not being used, and the compatibility configuration
information from the earlier version of PC/TCP is present:
