Still an issue in 0.16.1, easily reproducible!
Still happening in 15.4, reproduced it basically as soon as I created a new world.
I didn't mark the issue as private nor do I like being told off for posting something that I TRAWLED through the website looking for a similar case. There wasn't one, so take back your comments, thank you.
Having the same issue. Trying to play a LAN game with my Windows 10 and my son's Pocket Edition using the beta. PE disconnects from server, my computer perpetually leaves me on the screen seen above and I eventually have to close out the window.
