FixedColumns+ColVis + jQueryUI, strange problems

Hi all,

To illustrate my problem better, I've put together part of my code in this jsbin
http://live.datatables.net/azohes/53/edit
(press the 'generate table' button)

I'm using FixedColumn, ColVis, Scroller, set bJQueryUI=true and apply a theme

Below are some strange things I observed:
1. Cannot sort by the 2 fixed columns, other scroll-able columns work fine
2. Misalignment between header and content for the left-most fixed column ('ID') (could be an empty space causes by the sort arrow icon?)
3. Show both hidden columns in ColVis, column headers in scroll-able area is taller, while those in fixed area is not changed

This error shows up while doing some of those
Uncaught TypeError: Cannot read property 'className' of undefined , in FixedColumns line 796

Setting bJQueryUI = false solves problem 1. and 2. but 3. still exists.

PS. Is this the correct way to call dataTable multiple times (after a user has changed some input)? or I could do some kind of table refresh if the dataTable already exists?

Any suggestions regarding these will be very appreciated.
