Hi Alan, Peter,
I have ran example x07c under bare Windows - there was no problem with the PostScript output. Both symbols appear in the PostScript file, just as in the graphical window. The symbols appear to be drawn though as Hershey symbols, the arrow head is a triangle made opaque with a couple of lines, not a filled triangle. I have not studied the actual rendering in any deep way (a trifle involved for the morning of a busy day), but I suspect that this might be the underlying cause.
