#7 Navigable checkbox backwards meaning

[Anonymous]

When the "Navigable" checkbox is checked for an
association, the arrow is hidden; when it's unchecked,
the arrow is displayed. Unless I'm mistaken, this is
backwards... it should show the arrow if it's navigable.
(Ref. Fowler, UML Distilled 2nd ed., pg. 55-56)

Also, while it may not be common, UML allows
bidirectional associations, but UML Sculptor doesn't.
