Instead of text input boxes appear gray zone.
When I turn TeamViewer everything returns to normal.

I to have this problem.

Also virtualbox virtual host only adapter stops neighbors discovery - solution if possible is to disable adapter.

I edit my first post and add info.

I forget what the option is called. But on your windows you have a double arrow next to the minimize/maximize buttons. Disabling that feature in teamviewer fixed my problems.

Not only with Teamviewer. Generally, if you run any application that displays extra buttons on other applications' title bar (as teamviewer does), then winbox3 will be very, very unhappy...

Yep, i find in Advanced options "Disable remote integrations drag-and-drop"
But problem still exist with another extra buttons.
I hope that the next version of the problem is corrected.

Thank you for your help.
