Flexigrid with IE6 show only headers [SOLVED]

Question

I'm using flexigrid with jquery-1.2.3.pack.js, works fine with firefox but when i try ie6 it show only headers.

Searching on the web i've found a discussion on the same bug, and it says to comment this line from flexigrid.js:

if (p.width!='auto') g.gDiv.style.width = p.width + 'px';

Tried with this but it dont show the grid anyway...
