[Pixlib] How to cancel LibStack loading ?

[Andrzej]

Hi All!

I'm new to pixlib and making first steps.
I went trough some tutorials (few due to no documentation) and I'm
trying to make a simple gallery.

My gallery loads images by GraphicLib instances and LibStack.
The problem is, when flash loads some images to clips and I try to
switch my gallery, loading the 'old' list should be canceled or
paused. How can i achieve that?

P.S. Sorry for my post and my english ;)
