When you click to like a post, a confirmation request pops up. Is this new?
Edit: Here is the code that breaks things, probably because of ill-formed quotation marks:
[CODE lang="java" highlight=""15-17,25,""]public[/CODE]
If I include this then saving an edit doesn't work properly and replying to the thread is difficult as well (see the following post). If I don't include it everything is fine.
