Yep, selecting "clear" during your task wipes all the stats.

Selecting "direct to" anywhere has the same effect - because it clears you task.

But judicial use of "activate" and adding waypoints does what I need. You can also unactivate a cylinder by activating the previous one.

The IGlide program is excellent. The documentation, not so much. You just have to play around with it to find out what it does.

And my wife thinks I'm silly because I use iGlide to navigate to work and to the grocery store!
