Shared library blues

Hmmm. Been trying to find some threads to save my head on this one…

I have a main movie, which loads project1.swf into a container movieclip in the main timeline. project1.swf is also a shared library of image movieclips, which once loaded is used in the main movie, in scaled thumbnail movieclips.

Problem is, although these linked library movieclips are visible when I’m building the main movie (in the thumbnail movieclips) - when I export it, they don’t show up, although the library movie, project1.swf seems to load in fine.

I’ve checked the linkage for both the library movie and within the main movie, and all seems OK.

Anyone help me out of this hole, or point me towards a thread of wisdom!

Thanks all.
