Since Split View came out I've been using it with Messages and Skype with no issues. This morning I got an update for 10.12.1 and now when I put Messages in a window with Skype it takes up the whole screen and covers Skype up. I thought ok maybe it's just an issue with it sharing with Skype, but no I tried putting it with Mail and it does the same thing. Why do they break things that work perfectly fine? ARRRRGGGHHH Can anyone else confirm this error is happening to them?
