Something has changed and I'm not sure what it is. Prior to this issue drawing lines was pretty straight forward, click start point and draw to end point. Now I click start point and start to draw, the line segment I am drawing now shows angle and length information and when I want to place the end point the end of the line is very jittery at the point I wish to terminate it.
I know it is a switch(s) I have inadvertantly set, I just don't know which one(s)
