[jQuery] jQuery and Ajax conflicting only on macintosh?


I have a very simple script that fails on macintosh only (works on PC
browsers) when I include the ajax.js file. I am not even using it
(not in my simple script anyway, shown below). When I include that
file, the drag and drop no longer works on a mac.
Any help is greatly appreciated
You can see my two examples here:
WORKS: http://cmi2.yale.edu/test/cjohns/working_example.html
DOES NOT WORK ON MAC: http://cmi2.yale.edu/test/cjohns/nonworking_example.html
The code is as follows:
<HTML>
<BODY>
<!-- THIS NEXT LINE IS THE ONE THAT STOPS THE SCRIPT FROM WORKING ON
MACINTOSH -->
<!-- <script type="text/javascript" src="scripts/ajax.js"
charset="utf-8"></script> -->
<script type="text/javascript" src="scripts/jquery-1.3.2.min.js"></
script>
<script type="text/javascript" src="scripts/jquery-
ui-1.7.2.custom.min.js"></script>
<UL id="listA" class="connectedSortable">
    <LI id=Aitem1>A - Item One</LI>
    <LI id=Aitem2>A - Item Two</LI>
    <LI id=Aitem3>A - Item Three</LI>
</UL>
<UL id="listB" class="connectedSortable" ">
    <LI id=Bitem1>AB - Item One</LI>
    <LI id=Bitem2>AB - Item Two</LI>
    <LI id=Bitem3>AB - Item Three</LI>
</UL>
<script type="text/javascript" charset="utf-8">
    $("#listA").sortable({
        connectWith: ['.connectedSortable']
});
    $("#listB").sortable({
        connectWith: ['.connectedSortable']
});
</script>
</BODY>
</HTML>
