Bizarre TOC bug from Find & Replace window

Just sharing really and not even a complaint - I've reported the bug - but this explains a previous loss of data I could never explain, and I thought it might help someone. RH9, Windows 7

1. Find and Replace in Files

2. Add a search term

3. Decide you've mistyped the search term

4. Try to edit the search term pressing Delete on the offending character

5. The field has lost focus and won't delete (it gets focus when you start typing a new character)

6. Look over to your left at the TOC window (if showing)

7. Your TOC entries are gradually disappearing as you repeatedly press Delete in frustration

8. DON'T save your project!
