XML scrolling thumbnails not working?

Hello all,

I have created an XML photo gallery with thumbnails that by it self works perfectly, the thumbnails scroll by placing your mouse over hit points as described in one of the great tutorials on this site.

My problem is i have 5 different photo galleries that i have saved as SWF files that load once a user clicks on the appropriate link. When this happens though the hit pointers move about 15cm to the left? So to scroll through them to the left your mouse needs to be at the far left of the screen, but the far thumbnails are in the middle of the screen?
