There is a single comment on my site that I can't delete. There is nothing special about it - it's just a regular user comment on a regular post. But it behaves very strangely! In the list of comments it looks normal at first:
http://rookiemag.com/?attachment_id=56249
But when I hit "trash" it doesn't disappear like normal; instead it is just faded out:
http://rookiemag.com/?attachment_id=56248
It doesn't go away after that -- when I reload the "All Comments" page it is always there, unfaded again.
When I look at the comment in "Pending Comments," all the action buttons (including Trash) are gone, and the comment appears not to be associated with a particular post:
http://rookiemag.com/?attachment_id=56250
I should stress that no other comments are behaving this way. The rest look totally normal! What gives?
