partial solution to the issue with "entered" branch

[Lakshman]

Hello Robert,

The attached patch tries to resolve the looping issue with the
"entered" branch of yours. I am assuming that you were referring to
this in irc today morning, I was sleeping then and missed it.

I need to still figure out the segmentation fault issue occurs after
closing or making another edit after it displays waypoints. I will
send another patch soon, where I have been working in a different way
to this problem.

Thank you,
Lakshman
