lines that don't delete

I've got a straight line that doesn't want to delete. I've tried everything I can think of to select it, even zooming in so far that the only thing is visible is this flipping white line! Anyone throw any light on the subject - and yes I know I'm asking a dumb question.

On my cell, but make sure on the layer it is on isn't frozen.
Sorry @JimP but I don't understand the first half of your reply but I don't freeze layers - way too complicated for this poor wooden top
Which line are you talking about? I'm not seeing ANY straight white lines in your FCW file.
There are several fractal white lines, including one extremely small one right on the coast (which might be considered straight), but all of those can be selected and deleted as normal.
The four straight lines are dashed, but are Colour 29 (pale cream), and form a single group (all on the "latitude" Sheet). However, they too can be selected and deleted as normal.
Is this perhaps not the FCW file you intended to post here?
here is a screen shot of the fcw
That line is a visual glitch. It is caused by a very small overlapping line segment right where that artificial line hits the coast in the bottom center. I didn't get the glitch, so for me it just looked as a tiny dot near the coast. You should be able to get it if you zoom in to that area where the land meet the sea (and the line) int eh bottom center. Note that while selecting it at that point., you will probably end up selecting the landmass too since it is right on the coast, so deselect the landmass by holding down ctrl while clicking somewhere else on it before you "do it".
so theoretically I could leave it alone for the moment?
I hid the Land sheet so that I could click without worrying about catching it and it was simple.
'On my cell ' means I'm on my cellphone and can't check the fcw.
what causes the lines to be phantom lines? I've got another one and I don't know if it is something I'm doing that makes them - only the second one is much wider.
It's usually where 2 nodes on the same line are too close to each other. Have you ever used SIMPLIFY to cut out all the unnecessary ones?
no I've never heard about that command; how do I approach the command? Is it the same type of process as above?
I'm producing maps in different styles to make me learn more commands - next one will be a dungeon of sorts, as I've never got to grips with them. I don't to just map in one type or type.
You just type the word SIMPLIFY on your keyboard and hit enter.
That should bring up a prompt in the command line asking you for the Simplification distance and offering you a default distance in brackets. The distance is in map units, so if you want to change it type a new number in and hit enter.
You will then be asked for the path to simplify, which is when you pick your path (or polygon). The operation is immediate. You don't need to hit D for do it.
Undo works fine if you picked the wrong distance, so you can try it several times until you get the desired result.
The only drawback is it doesn't work outside the map border. If you try it on things outside the map border they just vanish. I'm also not sure if it works on multipolies. You might have to explode a multipoly before you can simplify it.
thanks Sue.
You're welcome :)
It might be worth considering if you might be using just a little too much detail generally if you end up having to use SIMPLIFY all the time to resolve these line glitches.
