'Clear links' not working

Windows Vista on a Dell Inspiron 6400. Scrivener Beta 1.55.

I copied and pasted some text in tables from Word into Scrivener.

A couple of the words had hyperlinks I didn’t need. Highlighted them, right-clicked, chose ‘clear links’ and nothing happened.

Tried right-clicking without highlighting - still no success.

Checked the ‘known bugs’ list and did a search on the forum - can’t see that anyone else has reported this bug, or have I unknowingly made a blooper?
