I have been working in Maya since it was Power Animator, 20 plus years so this is NOT a user error. Last time I used Maya (2014, yesterday) everything was fine. But today the extrude tool is totally busted. I can't extrude faces or edges. When I try to extrude edge ,nothing happens I try to drag what would be the extruded edge and all I do is drag the edge. When I try to extrude a face on a cube, it extrudes as I see the edges now have extra blue little squares for the new faces created, but if I drag the face, the selected face remains and just the edges move
