Are you sure you downloaded the correct version for your operation sistem?
If you downloaded the correct version, I dont know whats happening, try to talk with Sebastian.
You can allow us to put more than 8 inputs and some way to zoom in and out, and so the inputs Will be more tiny and it would fit in the display.
It also would be Cool adding some form of compacting the wires in just one. My suggestion is when You click in an input it creates a wire and when You click in another input without distroying the other wire it Will create a group of wires in just one. And of course a way to compact inputs of a gate, does that make sense for you?
