scrollX=true breaks IE8

hi, setting scrollX=true (or 100%) is causing the following script error in IE8:

Message: Invalid argument. Line: 57 Char: 471 Code: 0 jquery.dataTables.min.js

I've two example pages here, one where scrollX=true and one where scrollX=false If I load these pages in IE8, I get the script error for the one where scrollX=true

http://sungard1.coastlinesolutions.com/dataTables/scrollx_false.htm

These are trimmed down pages, whether horizontal scrolling is required or not the behaviour is the same in IE8 anyone had this?

jquery 1.10.2 datatables 1.10

thx
