One issue is that there's a good chance evince won't be installed on 
win32 or OS X.  I'm a bit unclear on what you're doing though.  I'd have 
thought there'd be a preview widget that would need to handle expose 
events and render as appropriate.

As far as the question about about print dialog modality, the win32 
dialog api is designed to block until the dialog is closed.  It might be 
possible to work around this using threads, but it would be ugly.  I'm 
not entirely clear on why the helper app needs to be closed before the 
dialog is closed, though.
