The problem could not have been carried over from Ventura; there was never any problem before the "upgrade". Also, the new Mail program has removed one of its best features; the ability to manually sort a message into the correct mailbox with one click. Instead of a button showing the mailbox, you now have to right click and then click again on the mailbox name. So instead of one click, it now takes one click, scroll down, and then another click. Very annoying. Do Apple developers every use their own applications? I can't imagine why they would remove such a simple and useful feature.
