Preloader Breaks External Class

Hi All-

I am pretty sure this is just an I’m an idiot moment, but I am having a problem with a scrollbar I created when I use an external preloader. The scrollbar is defined in an external class and works just fine when I compile that SWF and also when I view it. When I load the main SWF through the preloader, I lose any functionality on the scrollbar.

Its like the preloader SWF strips the scrollbar class definition from the main SWF. Is this possible? Does anyone know what’s going on here?

Any insight is much appreciated. I imagine I am linking the external class incorrectly or something- not sure…

thanks,
michael
