I now have the following code, that creates a 3 page output.  

***NOTE***:  I am using the "ms" macros to create it, so that may have
some bearing on the problem.  The commandline being executed is (it is
my standard invocation):

  groff -etpU -ms -Tps file | ps2pdf - > file.pdf

and the file reads:

.LP
.PS
box height 0.3 color "black" "foofoo" shaded "yellow" ;
arrow arrowwid 1;
box width 3 height 3 shaded "grey98";
{"foofoo" at last box .n + (0,-0.1);}
box  width 1.8 height 1.5 shaded "pink" at last box .w + (1.5,0);
.ps 8
{"\fBfoofoo()\fR" at last box .n + (0,-0.3);}
.PE

.\" Pod gets a black box - change "gray" to "grey98"
.PS
box width 3 height 3 shaded "grey95";
.PE

.\" Pod gets a black box - drop the "98" and see page 2
.PS
box width 3 height 3 shaded "yellow";
.PE

.\" *Failure with:* both the following - OK, see pp. 2 and 3
.PS
box width 3 height 3 shaded "grey";
.PE

.PS
box width 3 height 3 shaded "grey98";
.PE
