Adding thumbnails - moving the scroller?

Hello everyone!

I am using the Kirupa gallery with thumbnail scroller - which is a FANTASTIC gallery system!

I want to move the scroller but when its moved further right…the scroller stops working. I can move it up and down on the stage, but once it goes a certain distance to the right the thumbnails do not load.

I also shortened the mask to about 160 px so it only shows 3 thumbnails of my pictures.

Here is a link to my FLA file: http://www.frednordahlconstruction.com/thumbnail_final.fla

How can I get this to work? Why wont the thumbnails load once the scroller moves a bit further to the right!
