using lion.. and all updated etc.. mail doesn't quit either by the red light or left click in the dock. only way to quit is force quit even though its not listed as not responding
I have experienced the same issue. Whether I use the pull done menu or by clicking the app in the dock. It sometimes takes 3-4 attempts before it will close. Any suggestions or ideas on what I am doing incorrectly?
The red circle has NEVER worked to quit Mail. I've been using Mail for years, and it always stays open even if you close the last window. In Lion, you might be able to get it to auto-quit after a while, but that doesn't mean that closing the last window quits it.
If you use IMAP, you might want to try and delete the local mailboxes. There could be some sort of corruption going on there. You should also check your sync settings to see how exactly the mail is being synced. I find mail very finicky and it can often hang with almost no reason.
