Netscape7 and embedded javascript in xsl stylesheet

I have an xsl stylesheet that builds an html page with a simple
expanding/collapsing tree from some xml data. I can get it to work fine in
IE6, but the javascript <SCRIPT> tags that link to external .js files seem
to cause a problem in Netscape 7.  I get javascript errors that particular
functions don't exist.  And the browser just keeps churning--the page never
fully loads.

So, it appears that the the external javascript files are not fully loaded
into memory before subsequent javascript is executed.  By the way, these
.htm and .js files work fine when not rendered via xsl.  I'm trying to
reproduce my hardcoded htm file using xml+xsl.

Thanks for any help you can offer!
