Help! with XML slideshow thumbnail scroller

Hello all! I’m new here. I did the couple of tutorials for the XML slideshow and how to add thumbnails in a scroller to it. I used that to modify a photo gallery, I’m working on. So It’s working fine, except for one issue.

When the thumbnails first load into the movie clip- they are shifted slightly to the right. Then when you move the mouse and activate the scroller on the right hand side- they will shift to the appropriate position.

Has anyone had this problem? I can’t figure it out. If this isn’t a common problem, I’ll repost with an .fla.

Any help much appreciated.
