shared library hates frames

I've got an AS3 movie with multiple frames, each with an instance from a shared library. I've got the assets from the shared library importing on frame 1, with the actual content frames on 2, 5, and 10.

Viewing the frames in order works fine. However, if on frame 10, I go back to frame 2 or 5 using this.gotoAndStop, the frames appear blank. If frame 10 goes back to frame 1, then frame 2 looks fine again. Even better, in the flash IDE test-movie, things look fine. In a browser (firefox on windows, player9.0r45), the above issue occurs. What the heck is going on? Is there a better way to get shared library content to work?

Just found this: http://www.michaelhagel.com/?p=60 which seems to be the same problem. That page indicates that using an absolute URL for the library may fix the issue. I haven't tried that. Is there perhaps some other way? The movies I'm working on will be deployed to several intranet sites and we cannot assume any particular absolute URL will be available.
