I still see balsa lockup.  I built balsa today from CVS where the
latest Changelog entry was:

2001-04-03  Pawel Salek  <pawsa@theochem.kth.se>

        * src/main-window.c: lock GDK in balsa_window_progress_timeout().

Balsa still locked up when I clicked on a mailbox to open it, here
are the gdb traces for all active threads:
