One of our users complained that the MM toolbar disappears on the next run of Writer even if they enabled it manually via the View - Toolbars menu.
It would be nice to have the toolbar remember its position, if it was enabled manually.
Currently it appears automatically if there are database fields in the document or the MM wizard was run.
User expectation is that they should be able to keep the MM toolbar always displayed if they wish to, similarly to Word, which displays the Mailings ribbon by default.
Sounds like an ordinary bug. Jan-Marek and Maxim, you are the experts for MM and toolbars.
Mike, there is a bug about your love MM toolbar :D
