Scrollbar reset problems

I am using the scrollbar script provided by Claudio. The scrollable movie contains buttons that when clicked bring a movie clip into view - over the top of the movieclip that contains the scrollable contents (main).

At the moment when the new movieclip appears I am using actionscript to hide the scolling movie so its buttons aren’t active behind the new movieclip.

_root.fade.content.special.main._visible = false;

However, the problem is this:

When I then use

_root.fade.content.special.main._visible = true;

after the new movieclip has been closed to bring the scrollable contents movie clip into view agian the scrollbar has reset its position to the start.

Is there a command, instead of making the scolling contents movieclip not visible, that will disable the buttons temporarily so they don’t cause confusion when there is a movieclip in front of them? Either that or a way to gain the position of the Claudio scroller so that you can set its initial position back to where it once was?

I hope this makes sense!

Thanks
