I've had PC-XView running for quite awhile now, with GRASS, so I've
forgotten how I corrected that error, but I do remember it.  Do you
have Microsoft Windows running in 256-colour mode?  I don't think 
it will work in 16 colour mode.  Also the PC-XView startup preferences
I use are:

  Default visual class:    Dynamic
  Use windows system colours (oops, spell that American: colors)
  Window Management:       Remote.

I run Motif then, on the UNIX side, once I have connected to it,
simply by entering the UNIX command 
  mwm &

I don't remember what, if any, of the above might be relevent.  Let me
know if you continue to have trouble, and I'll try a bit harder to
help you figure it out.

Tim.
