Multi Monitor and Sierra Forgets Window Positions after Wake Up From Sleep

I have a laptop screen and an external monitor. Both are open during my workday. I keep my email and Messages app on my laptop screen and use the 27" monitor as my primary display for everything else. It's basically a multi-monitor setup except my laptop screen is the second monitor.

About once a day, when I leave my Macbook Pro Retina for 30 minutes and it goes to sleep, I wake it up from sleep and all of my windows are moved to my 27" display. I have to drag my email and Messages app back over to the laptop display.

Unless I physically disconnected my monitor, this absolutely never happened in El Capitan or Yosemite and even Mavericks. Every time I work up my Macbook from sleep it would remember where the windows need to be.

Why is this happening with Sierra?

Yes, you are right: there is a small lag that disappears when the when the panels are turned off.

Not a show breaker though.

Unfortunately, it only seems to have worked once. Now iTunes in particular refused to honor the Space to which I've assigned it. <sigh>
