Ahhhhh. Thanks steve. That may well come in very handy. Perhaps I'll go and get some video of that car-park now, after all.

It's 1/4 to 1 in the morning and the prospect of trying to explain myself to police who want to know what I'm doing in a car-park at 1 in the morning with a video camera and a measuring tape didn't really thrill me.

Though, I guess I'll still need to get em at some stage..

Much thanx, yet again mate.
Si.
