Hi.
I noticed that you want to create a global exception handler for dabo. I
have created something like that for use in my wx applications that
might be of interest. It's far from complete, but you can see the basic
concepts. I wanted to be able to automatically send error reports to a
specified e-mail upon crash (not yet done, but not to big change
needed). So far it just catched unhandled exceptions and writes a
crashlog and has basic logging capabilities. Still, you might be
interested in having a look.
