Interesting construction line behaviour and possible bug

Hi Michael,

But now I'm getting an error.

This happens every time I click on one of the construction lines. In previous versions you could click on the line and delete it or move it. Hopefully this can be put back the way it was.

Of course it could be something I've done in the SidePane.htm file, but I haven't made any mods that I didn't do before.

The ZIP has the 3dm file and my edited SidePane.htm.
