Allowing only one flash movie to load at once

hi,

I’m not sure where to put this… but anyway… I wanted to ask… is there a way to make it so that on any one computer… only 1 instance of my flash movie will run?

Like if they go to a site… with my flash movie on it… and they open up another tab… of the same page… only one of those flash movies will run…

lol I can’t seem to explain it better… but i hope you can understand!
Thanks!
