Please don't assume that. What you said sounds reasonable but I don't know these portions of the code very well. I was and am currently answering from my phone where I cannot look up the code to check. 

I think it can be done without a second table. Just locate the loop that becomes infinite and make sure it ignores dp's that are not edited. That should make it finite. 

The other thing is to clean up the calculated waypoints upon change of the entered ones and recalculate the computed ones.
