Dynamic library loading

An old chestnut…

Using shared font/asset libraries is pretty straightforward, but i’d really love
to know how the dynamic loading of libraries at runtime works. I’ve
searched everywhere on the web and seen a few people claim to know how this
is done, but not one single step by step solution. Since there are solutions
for almost everything else, I guess nobody really knows. I can buy a
solution at sharedfonts.com, but i don’t want to rely on a commercial
solution where I can’t see the source even when i’ve bought the product.

It can’t be that hard…can it???

All I want to do is load the fonts as required, not all on the first frame.

Please help: I must have browsed thousands of sites and google responses and
unless this is the most difficult subject in Flash someone must know the
trick and i’d really love to know.

Thanks in advance

Bob
