I've had the same problem with the "pstack" command - the machine just 
hangs ( an 'input queue lock', I think ). I guess this is just the result
of unfinished software - it _is_ in the Demos !!

The answer is not to use PageView, but to use psh instead. In case you didn't
know, then you can create a PostScript/NeWS file with the top line

#!$OPENWINHOME/bin/psh
  ^^^^^^^^^^^^ ie, insert the home directory of OpenWindows here;
               mine looks like '#!/openwin/bin/psh'
               (Assuming that's where psh actually is ! )
 

Remember to do a 

% chmod u+x <file> 

and then just run it. Of course, this does mean you have to create your own
canvas to work on. ( NeWS 2.1 Programmer's Guide tells all ).


Hope this helps.

David.
