[jQuery] jQuery slidable pananel with mouse over + gMaps + IE = SLOW!

[sosamv]

Hi guys, Im creating a informative dashboard using googlemaps,using
marker manager and some other stuff, I also have a panel on the
left... we can click on each one of the options and it will do
something like $(this).next().slideToggle("slow"); and this function
is also looking for all of the other elements and its collapsing them.
the problem is that i'm importing a bunch of files:

<script src="http://maps.google.com/maps?
file=api&amp;v=2&amp;key=ABQIAAAAnfs7bKE82qgb3Zc2YyS-
oBT2yXp_ZAY8_ufC3CFXhHIE1NvwkxSySz_REpPq-4WZA27OwgbtyR3VcA" type="text/
javascript"></script>
<script src="../js/markermanager.js" type="text/javascript"></script>
-----------------5kb
<script src="../js/principalMap.js" type="text/javascript"></
script>-----------------3kb
<script src="../js/jquery.js" type="text/javascript"></script>
-----------------55kb
<script src="../js/principalMenuAjax.js" type="text/javascript"></
script> -----------------3kb

Everything is working smoothly on FF, but as I mencioned, IE is very
slow if i remove the imports for the google map or the marker manager
everything works fine.

What should I do?
