Buttons up / down state

Hi

Does anyone have a solution for creating a Flash button over state - with the over state reverting to ‘up’ mode when another button in the menu is clicked.

I know this can be achieved by creating buttons as movie clips - and then actionscript to handle the recognition and actioning when another button is clicked - sending the other buttons timelines to the up state.

But this is a script heavy solution.

Presumably a function could handle this best - any suggestions on what that function would look like - or links to tutorials providing a template for acheiving this using a function?

Many thanx
