Short description of error
Its as simple as I can't use the third click of the mouse to move around even though I have checked the mapping and it does say that the middle click is to rotate around. This did work in 2.79 but I can't move around with the third click. I don't know if the fact that I use Steam to launch Blender could affect anything.
Exact steps for others to reproduce the error
I open Blender, hold the middle click to try to move around the viewport, viewport doesn't move.
