Preloading Shared Library

Hi. I have a little question.
I want to preload a shared library, how do I do that ???

It’s built like this.
[COLOR=Red][main file] --(loads)–> [anotherfile] --(holding shared things)–> [shared library][/COLOR]

I have my main file that loads another swf. In that swf I have a shared object from a third file that I want to preload.

The problem is that the file I’m trying to preload actually don’t have this shared object until it’s fully loaded. So If I try to preload it, it’s just 2kb. The shared file is about 15/30kb.

Best Regards
