Interesting...  Is the whole Framework now considered deprecated legacy 
code, or just its file dialogs?  I was using the Framework in an attempt 
to get a lot of basic functionality taken care of quickly.  In 
particular, I liked that it gave me all the basic menus with mostly 
sensible versions of their actions.  Is the recommendation that I use 
the Framework menus and the method file-menu:open-callback in order to 
set up a variant of handler:open-file that uses the GUI-level get-file 
and then calls "handler:edit-file to open the file, once the user has 
chosen it."?

I'm not getting much of a useful error-report / stack-trace, which may 
be because of some try/catch forms I've got wrapped in various places.  
I'll probably come back to this one another day, either to try to get a 
better trace and/or to build a simplified case...

Thanks.  I think I've got that working now.
