I'm still have wishlist problems as well. There's a very long delay before the boxes show up, and sometimes they don't show up at all. They don't disappear very well either after clicking the - symbol.

The blue outline reappears on a WL item I remove when I hover over another item.......

So now I'm having the opposite problem that I originally had when I started this thread. Now when I click the "+ wishlist" button on items, the blue outline doesn't appear at all, unless I refresh the page. It just changes to a "...loading..." option.
