Be very careful when doing the copy method!

In at least two opportunities I had worse problems afterwards.

After copying 'all' to a new file, it saves fine, but there is still a (hidden) problem remaining. Even
though, as reported, selecting started working again, but I had several crashes.

Eg. when simply editing the properties of a spline and saving again. Part of the drawing is
missing and LibreCAD hangs on loading *that* new file.

Do make a backup and change the new file's name so as not to loose previous versions!
