I only just became aware of this newsgroup, though I've been
trying to run ghostscript (1.3) for about a week now. Anyway:

I worked out a fix to this problem by replacing the
makedevice call in ghost.ps by a new function "changedevice"
which just resets the default device according to
the parameters usually given to makedevice.

Wasn't anybody bothered by the fact that the image is not retained after
being hidden and re-exposed? (Or did nobody have this problem? I'm on
a Sun 3/50, runnning R3.) Anyway, I have a fix to that too, by
putting everything into a background pixmap as well as onto
the window.  This fix also does away with the ridiculous getchar()
statement, since it makes no difference when the window
receives its expose event.

However, the changes I have made are somewhat incompatible with
Hal Peterson's patches so I have sent them to "ghost@aladdin" instead
of posting them.
