When previewing, the help text on the upper left is false (01 Sep 2001 release)
it says:
To cancel: Go back twice.
but it should be:
To cancel: Go back and click Cancel.
Otherwise beginners leave lock files everywhere...

A better approach from a usability standpoint would be to add a Cancel Edit link to the preview page.
