I'm using Apple's 10.4.4 Mail.app and have recently noticed that messages put in Mail's trash are no longer visible you click on 'Trash'. The trashed messages are still available as emlx files in
~/Library/Mail/acount_name/DeletedMessages/Messages
and when I ask Mail to empty its trash those files disappear in the Finder so the actual mail files are still around. But obviously Mail has chosen to not allow me to view them anymore.
The most obvious attempt at solving the problem would probably be to rebuild Trash, but for some strange reason I can't select 'Rebuild' when I've selected 'Trash'. I've tried setting up a new account, no dice. I've trashed prefs, no dice.
Has anybody else seen that happen? Is there a fix or work-around?
