i have returned to a drawing....its a roof plan and i have lines drawn all over it to replresent gas and power lines....i select a line and it moves....the screen jumps and the line that is selected moves as if its offset....i am not drawing a line (as when you draw a line with an offset from an existing line)...i am just selecting it to drag and then it jumps.....it just started doing thins....any ideas?
and its just when i touch (select) a line that the screen jumps
