This has happened with multiple databases…I drag a bunch of mail messages into EF (or use the F1 shortcut.) Eagle crashes. Then, when I try to reopen, EF crashes again, and continues to do so even if I manually remove the messages from Eagle’s finder folder. There’s no time for me to do a verify or any other maintenance upon reopening Eagle.
So far, the only solution has been to create an entirely new database and reimport everything (except the messages.)
