In Internet Explorer 8, I'm seeing a javascript error:

Invalid Argument.

jquery-1.3.2.min.js

Code: 0

Line: 19

Char: 31804

Examining the code in the uncompressed file, I found the cause is line #3908:

start = ((end || 1) / e.cur(true)) * start;

e.cur(true) is zero giving start the value of NaN

Sorry, I do not know what the cur function is or why it is returning zero.
