Came across a couple of other (visual) problems -

1. There seems to be a limit for usernames on the Who's Online panel on the left which causes their names to overflow out of the table (screenshot1) (screenshot2)

2. For some articles, the main panel on the right seems to go really wide (this seems to happen randomly, I've not been able to find any correlation between content and this - or maybe I've not looked hard enough Smiley (screenshot)

Cheers.
