Help with lostinbeta's mouse follow with ease tutorial

Hello-

I followed lostinbeta’s excellent Mouse Follow With Easing tutorial and made an animated movie clip of stars for my mouse trail on a site I’ve been working on, http://www.portfoliocenter.net/~da_werne/thread.html. It looks fine in most of the browsers I’ve tested it in, but in IE5 it seems like the trail is masking the background image ([url=“http://www.portfoliocenter.net/%7Eda_werne/whatisthis.gif”]http://www.portfoliocenter.net/~da_werne/whatisthis.gif). Any ideas?
