No functionality in Mozilla 3.5 and limited functionality in IE7

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Added THEAD tags around header row 
2. Placed js in place where web server could access
3. Included JS in webpage on Mozilla 3.5.30729 and IE 7.0.5730.11

What is the expected output? What do you see instead?
Expected floating header, got:
Mozilla: Nothing
IE:  Header floated but was stuck to the left side of the screen, however,
the actual table was centered.  So basically the header was picking up the
correct offset.

What version of the product are you using? On what operating system?
I got the version from the download area. Which ever that is.  I can't seem
to find a version number in the code.

Used on Windows XP SP3.
