I used to like Top Sites - but now when I wish to REMOVE a site from a box, whether by "dismiss" or "remove from history", it doesn't remove it - it either puts it in ANOTHER box, replacing the site that WAS in that box, and/or replaces it with another site I have NOT designated as a Top Site - I have 4 rows already, do not desire any more - but now I can make NO new empty boxes for something I want, and have a bunch of boxes with sites I do NOT want.

 This might be amusing as a Whack-a-Mole game - but I stopped laughing some time ago ...
