BUG - Displaying Map

[Roger B]

Also, sometimes the point markers don't always disappear after they are deleted from the position list.

You're not the first to report his. But I still have no idea where it comes from.

Maybe a "Refresh Map" key is required - F5?

I always wanted to avoid that since I believe it's an unnecessary action that the program demands from the user.

The latter would be a way of overcoming the former, not perfect I know but at least it would get round the problem
