Very odd problem scrolling images

Wierd this:

I have put this on a server for you to see here:

http://www.galaxymusic.co.uk/mockhome.html

Here is the problem, when you visit the page, everything seems fine at first, you press the home button and it works fine, now you press the scroll butoon and indeed this works fine, now then, something strange happens, go back to the homepage - everything ok BUT when we now return to the scroll page, it doesn’t work correctly, the central button displays the image in the wrong place. I should point out that both home and scroll buttons load in the external swf files to an empty movie clip

I used a component for this which I downloaded at the following site:

PS, it might take about a minute for the scroll page to open (I didn’t bother with a loader for this - sorry)

I hope you can help.

Thank you.
