Button in a Movie Clip - Maintaining the rollover state

programming flash
1

I’m trying to highlight the current ‘page’ / movieclip by showing the onrollover state in navigation display/button.

So the colour remains the onrollover state (in this case blue) while the particular movie clip/‘page’ is displaying. Changing when the user rolls over another button.

I have two issues:

  1. I understand I have to place the button within a movieclip and have been experimenting with button ‘02’ in the attached example.fla - however now I have done this the original action contained within the movieclip instance myScreen_mc is no longer working.

  2. How do I change the rollover state back (to display black) when a user rolls over another button (and displays that blue)?

Hope this makes sense - any help would be appreciated.
