Topic: Hide simpleviewer?/unload viewer?

I have a timeline based flash site. I want to be able to unload or hide the simpleviewer when a user pushes another button on the website. Right now, the simpleviewer stays in the foreground while the contents from other parts of the timeline load in the background.

How do I hide or unload simpleviewer to make it disappear?

If anyone can help, I would appreciate it.
