Apple Mail - Hangs/Locks Up - El Capitan
I've upgraded to El Capitan and since doing so my Apple Mail app freezes/locks up when clicking on a message. It only happens for about 5 seconds but has become extremely frustrating due to the large amount of time I spend with emails.
Running 16gb RAM and 2,5 GHz Intel Core i5.
MacBook Pro, Mac OS X (10.7)
