Is it possible to loadMovie only once?

Hey there…
I have a nice looking expanding vertical menu. It works great. The buttons call up external swf files and load them into a content area. Wonderful.
The one thing I don’t have is any content in the content area when the main swf first loads.
Of course, I can put a simple loadMovie command in, but this causes problems with the buttons.

Is it possible to run a load Movie only once, even though the swf keeps coming back to the same frame?

thanks…

Chris
