We recently built the Mit R2 tape on a Sun 3/140 running underr
SunOS4.0.   The Server works OK:  It will display clients running on the 
local host, and on a remote Apollo (The Apollo clients were supplied pre-
built by Apollo).

Unfortunatley, Clients built on the Sun refuse to open displays other than
"unix:0".   The Clients make use of Xt and emit the following message when
the "-display xxxx:0" option is used :

		X Toolkit Error: Can't Open display: xxxx:0

We have checked the obvious things including the -DTCPCOM in the XLib
make file, and have disabled Host Access control.   However, we have
drawn a blank.

Is this a common problem?   Has anybody got any ideas?   To put it
another way HELP.
