All of a sudden I cannot "free Draw" wires/buses. As in I am limited to only 90 degree lines, my cursor has the cross hairs on the point as it moves on the screen. It wont allow me to make a connection to a bus come down and out a t 45 degrees then run the wire across the page. if I want 45 degree routes I have to use the stretch function. Is this a shortcut key I have hit or something? I cannot find how to turn it off any where. It is driving me nuts.
