The attached dialog keeps coming up whenever I restart Minecraft and try to join a multiplayer world/server. I am not sure if this comes up in singleplayer worlds, but it happens when I try to connect to multiplayer worlds and servers. This isn't a problem, except for the fact that when I check the box "Do not show again", it comes up again when I restart Minecraft. 

How to recreate:

1. Open Minecraft - Windows 10 edition (not sure if it happens in the Beta)
2. Go to a server
3. Check the dialog box to not show the pop-up again
4. Restart Minecraft
5. Go to a server, and see the message come up again, even though you said not to
