Here's what I do.
1 Create content, add a teaser before saving.
2 Navigate to my teaser.
3 My teaser is there but there's nothing to click on.

If I create the content as above and, after specifying a teaser, click Preview, it works.

If I edit the teaser, I see the title Destination with an asterisk, but no form field. Click the question mark but it's not much help because I don't know what I'm supposed to see

Thanks for any help
