I've been using NeWS (1.1) on my color 4/110 (OS 4.0) as a graphics 
server for several remote hosts on a production basis 
for about 6 months.  I generate a lot of xy plots and
histograms in PostScript and display them using psview.
One small change was made to psview - if it finds an environment
variable NeWSwidth it opens a square window of NeWSwidth size rather than
asking the user to sweep one ( I got really tired of sweeping windows ).

The problem is that occasionally ( ~ 1 in 100 ) I generate a postscript
plot that crases the server - usually with an illegal instruction.
If I restart the server and send the same plot it crashes again but if
I change the plot in a trivial way ( rotate it by putting in a 90 rotate
at the appropriate place or change the arguments to the initial scale
call) the problem goes away.

Anybody have any idea what might be going on?
