This is a follow-up to a recurring problem with Mail. A couple weeks ago I asked about how to correct a problem of a mailbox "Writing changes to Disk" for minutes at a time, and repeatedly. I deleted the mailbox contents with "index" in the filename, and rebuilt the mailboxes (all of them, actually, not just the offender). The problem has resurfaced. Not only is it writing changes to disk in the activity window, but now it is doing it two times at the same time. The mailbox is my most important mailbox with over 3000 digests in it, and that may be part of the problem, although Entourage never did anything like this. I'm thinking I might be forced to reinstall Mail.app, but since it installed with OS X, I'm not sure how. I have a hard time thinking it's the prefs, because it's only this mailbox. Any guidance would be helpful at this point. Thanks. -- David R. Boag, DDS spikedds at bellsouth.net Dental Design of Kedron, LLC
