Locking problem - suspect it's badly behaved app

I've got a problem with locking when using Ghostview to display
postscript files on the server.
I'm modifying the files through my unix a/c and displaying them on
my pc via samba with ghostview. I had a look at the faqs which told
me that this wasn't a very good idea. However, it would make my life
a bit easier if I could do it.
My problem is that when I modify the file on the server I can't view
the modified file on my pc until some time later (basically, until the
lock has been released), even if I kill ghostview and start it again.
I had a look at the locking info (via smbstatus) and I found that when
I open the file for viewing with ghostview the postscript file is locked.
When I kill ghostview, however, the lock is not released. This is in
contrast to what happens when I open (for example) an excel file on
the server. In that case, a lock is created and when I close the file,
the lock is released immediately. Hence, I think ghostview is at fault.
So, my questions are 1) is ghostview at fault? 2) if so, how can
ghostview be modified to ensure that the file open and close
operations create and release the locks properly? 3) if ghostview is
not at fault, what is likely to be the problem?
