I have my 740b connected to my autopilot in my RV. Often, I'll punch in "direct to" but fly the airplane as required to avoid airspace etc. This often puts me quite a bit off the magenta line. I eventually reset the magenta line to my current position so that I can fly direct from that location if I wish. I've seen that when I do that, the scale of the map changes. It pulls out to show the entire route causing me to perform 3-4 button pushes to get back to the scale I was originally at. Can there be a "no rescale" function be added?
