Embedded sortable items acting silly in IE

Embedded sortable items acting silly in IE

Hey,
I just started experimenting with jQuery today and I think it's pretty
nifty. That being said I've come across some difficulties with
sortable items that are embedded one into another. The two lists
behave perfectly in firefox but in IE it seems like grabbing a child
component also grabs its parent container.
Here's is a link to the page with the code:
http://virtuo.ca/vm/ClientCentral/SchoolShareCMS/test.php (don't mind
the ugliness of my CSS, it's strictly functional right now haha :)) To
see how it breaks you would have to view it in IE.
I'm hoping that I overlooked something trivial but seeing how this is
my first attempt at something like this I'm not too sure how to
proceed. Any help is greatly appreciated.
