I have reported this before, I believe, but it may not be on the bug list.
1) Put your mail folder on a shared volume (over Apple File Sharing) 2) Open the Mail Browser window and select a mail with an attachment 3) Select the attachment and try to put it in the trash with a cmd-delete Now PowerMail will hang indefinitely. Even worse, if you ever select that piece of mail in the Mail Browser window again, PowerMail will immediately hang. (Actually, I think you can select it, it is on the mouse-up event that PowerMail hangs--hence you can drag the mail to the trash folder). The only fix is to delete the mail when you have loaded the mail folder from a local volume. This bug should be easy to replicate and (I hope) easy to fix. A
