Nuno,
  Rather than using the exit function to reset the state of the
plugin, it would be better to have a "clear" or "reset" button to
start a new "session" within your plugin. If you look at complex
plugins like multiseq, this is more or less what they do. You can
create and destroy sub-windows, it's only the main plugin window that
needs to stay around to avoid creating difficulties with the way it
shows up in the Extensions menu. The APBSRun plugin creates extra
windows in some cases which are subsequently destroyed, for example.

Cheers,
  John
