Messages was working fine in the latest DP for about a week.. Now it just beachballs if i mouse over it. A couple of times i've accidentally left it running in that state and come back to my computer to a "low on system memory" pop-up. In activity monitor Messages was taking up 60GB of RAM! I have 16GB of RAM.. But yeah, does anyone have any idea how to fix this? I use screen sharing a lot to help family members out with stuff and can't at the moment. Thanks!
