unloadMovie Script

=) Hi people, this should be an easy one…

Basically, I have a few buttons which load SWF’s. the SWF’s are games. I need a script which i can add to the buttons so the SWF which is currently loaded is then TOTALLY unloaded.

Only reason I ask is because when some of the games are loaded for the second time they dont work properly and i thinks it because their scripts try to keep defining variables that already exist, so I need to unload them completely.

Anyone got any ideas???:h:
Thanks in advance.
