[Middle Mouse Button]

Yeah but only for the dual flying controls, but not for building.(For some reason my MMB is owrking now, so thanks anyway.

 

Also I found another problem I have with version 5.2, it seems my antivirus blocks it, it exactly blocks the command window that opens parallel to the game.

I have avast! and the feature that blocks it is the DeepScreen.

[Middle Mouse Button]

Is there a way of changing the use of middle mouse button? like for selecting blocks?

My button doesn't work so I can't delete blocks.
