Hey guys, just wondering if anyone else is having this issue. I have a MBP and I use Safari in full screen. Since the latest update, about once an hour, Mail suddenly pops up and pushes my full screen into split screen, and I need to minimize it back out of the full screen view. It's usually after it gets "login failed" for a second it seems like. I've tried rebooting, quitting, etc, but it keeps glitching. Any ideas why or anyone else dealing with this? Thanks!
