I have tried exhaustively to lock down comments in relation to their
respective cells.
Regarding the 3 options:
Move and size
Move but don't size
These seem to do something but nothing rational. For example,
Move-but-don't-size will not lock to the associated cell, but I can't see why
not. When I insert a row above, the comment (upon editing) is not in the same
relation to the cell as before.

Any ideas?

Thanks,
Mark
