kiketable_colsizable, resizing columns after width attribute applied to cell

I have successfully used this plug in to create draggable columns on a basic HTML table and with extra code suceeded in saving the new column widths to a database so that the next time the page is loaded, the table appears with the columns correctly resized.
 
However, if the user subsequently tries to resize these columns the plug in no longer works properly. The "ghost" shadow resizes, but the table cells will not resize smaller than the current width that is applied to it.
In a three column table, grabbing the right hand handle of the middle cell seems to be controlling the handle to the left of the cell.
 
I'm sure this is likely to be something I've done to cause it but just wondering if anyone had any ideas how to fix this?
I have tried using jQuery to remove the width attributes on the table on mousedown since this is the only perceivable difference between before and after but this doesn't seem to have had an effect.
