Maybe this is the same phenomenon as with the VotingBar, where the right border is sometimes outside the window (especially if nobody has voted yet).

I've struggled with replicating this. When I'm in the mood to fix it, I can't replicate it. When I'm browsing and not in 'dev mode', it doesn't do it. If a post having no votes is an indicator, then I'll be on the hunt for that!

Or the PayoutPane, which is partially displayed outside the bottom edge if there are no comments yet...

I've fixed the bug where the downvote button doesn't appear if you're at the bottom of the screen (although not merged it in yet as I don't want to confuse things) but not played with the PayoutPane.

I'm really not happy that this is the problem. The fix has required the removal of 2 styles but since the component is used in other places, I now need to find a load of other scenarios to test.

I'm away this week but trying to get some work done... which means my link to my dev server is unreliable and I can't upload.
