Flash File Shows on one server, but not another?

I have no idea why, but a lot (but not all, which is weirder) of the flash movies I do Will show properly locally, on my service provider, on our live server, BUT not on our internal staging server.

It loads the html page, and when I right click on the right area I get the “about macromedia” pop up, but the browser says “done” but no movie.

What could I be doing wrong? Or what could be screwy with the server? Anyone ever see this?

I don’t know if you want to see the fla or not, but I can post it if you want - it’s really straight forward though.

Here’s the link to the movie. (well, the page that shows the movie)
