In the new version of bugzilla for Thunderbird, I hit an 'enter' and it submitted the bug before I had finished entering all the fields. This is a really serious problem. Problems should never be submitted until the "Commit" button is explicitly pushed.
what browser were you using? this is a browser 'feature' for the most part.
Yeah, this is a feature, not a bug, although perhaps browsers should (or already do) allow you to disable it, and Bugzilla might consider allowing you to clean up more of the damage from premature submission than it currently does (i.e. by letting you edit the bug description).
clearing target of DUPLICATE/WONTFIX/INVALID/WORKSFORME so they'll show up as untriaged if they get reopened.
