Can't select text on ROOL forum

Something strange today: I can't select text from items in a ROOL forum. Wherever I click, the cursor turns into the hand, and all I can do is drag the page up/down/sideways. I can select text on the BBC News website, though. Can anyone tell me whether it's a result of the changes that ROOL are doing to their website or whether it's a new problem with the latest NS builds? I've tried r11907 and r11922. Dave
