Preloader wont allow site mc's to work

Hello,

I am building a site for a friend, you can see a rough example of it at…

Interchange

Problem is that when I put a preloader in the first frame which requires a stop action on frame 2, it stops the information windows from opening. (the info windows appear when the red circle is clicked - see online version above (its quite big so give it time!))

… so I’m a bit stuck, i’ve tried putting the loader in a new scene, but that didnt seem to work either.

Can you help?

I have attached a small .fla file with this post that follows the same priciples as the main site.

I await your solutions!

Mr.Craig
