We had this problem as well so I fixed it.  I asumed that our psroff must
be different from the one they use at Sun since it clearly worked for
them.  The fix is to add the line 

	0 0 moveto

to psview.cps as shown below

    cdef ps_startpage()
	/@DictHeight countdictstack def
	@Dicts length 1 sub -1 0 { @Dicts exch get begin } for
	PGC {
	    /@DictHeight countdictstack def
	    @Dicts length 1 sub -1 0 { @Dicts exch get begin } for
*	    200 dict begin
******	    0 0 moveto
    cdef ps_endpage()
*	    end
	.
	.
	.

You might also want to add the lines

	200 dict begin
	.
	.
	end

as shown above since there are many PS programs that define lots of
things on each page.  I have sent these changes to Sun.  Hopefully
they will be included in the next psview.
