I have had this happen on occasion in using Mail since 10.0.0 on many Macs but it has been rare, usually related to or caused by a particular email, and very rare with recent Mail versions. Update to 10.3.3 and then apply the recent security update. Both have a newer version of Mail. If this doesn't work, try trashing the file com.apple.mail.plist in Library>Preferences of your Home folder--you will have to re-enter your preferences if you do this. -Bill On Apr 10, 2004, at 2:59 AM, Da Pen wrote: > Woe is me.
