I'm encountering an error loop in mail.app that I can't get out of. I get this error message over and over again until the program crashes. I was at a meeting today in a building without internet access. While there I composed several emails and made one todo. Now the error message just repeats as I press OK until mail.app crashes. Upon relaunch, again. There is an INBOX.Apple Mail To Do folder and each time I press OK it adds another todo. I've tried deleting them all, but they just keep reproducing. The emails I wrote while offline have been sent successfully. I am running 10.5 on a SR MBP which is stock other than I upped it to 4G ram last week--with no noticeably related issues. How do I get out of this? Thanks.
