Thanks in advance for helping me out here. I'm troubleshooting my sister's iBook running 10.4.6 and we're 7 time zones apart, so things take a bit of time to coordinate. Her report to me was this: she opens up Mail.app, gets through the load process, sees her mail for about 2 seconds, then the app crashes. So far (this morning) I've tried the following: reboot, repair permissions, trash .plist files from both her user account and the main mail folder, all to no avail. So, any ideas? My next thought was to dump the LSMMap2, which I think is a junk mail filter. If that doesn't work, maybe she has an HTML message with a 'bad' image that's trying to load? If so, how would I disable html image loading without being able to run mail.app? Would disconnecting from the network first keep this type of crash from occurring? Thanks for any help you can think of.
