I found it now. It's a blank button as you said. Just didn't notice it before. Thanks.
Martin - its one of those tracks that grows on you isnt it! Oh and is the MMG F1 mod realeased? I thought it was still beta? If it is your one lucky b**ger!
The track cost 1.5 Billion to build and as I said to a friend last night, when he said it reminded him of silverstone, whoever designed it has clearly looked at all the best bits from other tracks and used that influence in the final layout, and I think its great.
