[jQuery] $(document).scroll() not functioning in IE?


I added some fun infinite scroll functionality to my employer's blog.
http://molecularvoices.molecular.com/
All of it is based on a $(document).scroll() event that doesn't seem
to fire in IE6 or 7. My alert() debugging shows that IE won't enter
into the function attached to the scroll event..
You can test on the above link.
Any ideas?
