Bug report v5.0.1 b135 - Screen HedgeHog not responding in session

Hello,

When I try to connect a hedgehog to a roadhog with ‘connect to show’ the screen of the hedgehog turns to black. When I start a new show, the screen responds as usual and I can use it properly. It seems to be a bug when I try to connect to show. There is no clash with IP addresses and I put in correctly another Net number and so. When I add a external screen, connect to show, I can use the external screen but the screen of the hedgehog is still black. 

Also when using Pig+Open+Backspace there is nothing to see and all seems to be ok.

Hopefully someone can help me out!
