Bizarre Shared Library behavior

I must be missing something.

I’m trying to set up a Shared Library.

I created one Symbol, set the Linkage to “Export for runtime sharing” and put it on the stage. Publish, looks great.

Whenever I create a second (or third or fourth) Symbol and set it to “Export for runtime sharing” it won’t appear on the stage, and further creates havoc with the first Symbol already on the stage, changing it’s appearance when published.

AND, when placed into a .fla that’s accessing the Shared Library, the second or third symbol when placed on the stage also won’t appear when I publish that file

The URL for all Symbols is the same, library.swf, and it’s in the same directory as the .fla.

I’ve read the tutorial here on Kirupa. Any ideas??? Thanks.
