Input boxes in tabled disabled when using firefox

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add an input box to the sample default.html table that is on the wiki, I 
just replaced <td>Win 95+</td> on the first table row with <td><input 
type="number" size="3" maxlength="3" min="0" name="ib1" style="width: 55px;" 
value="" /></td>

What is the expected output? What do you see instead?
The textbox input is disabled in Firefox, you are unable to click in box and 
enter data into the field, worked in version 1.0.

What version of the product are you using? On what operating system?
RowReordering 1.2.1, Windows 7 x64, Firefox 23.0.1

Please provide any additional information below.
I upgraded from version 1.0 which worked fine so some change from 1.0 to 1.2.1 
has broken input boxes.

Turns out it this can be fixed by removing ".disableSelection()" from 
$("tbody",oTable).disableSelection().sortable({ on line 202
