gird setBodyOverflow and freeze column

Hi, I have problem on

<gwtVersion>2.4.0</gwtVersion> <smartgwtGroupId>com.isomorphic.smartgwt</smartgwtGroupId>
<smartgwtVersion>3.1-p20140110</smartgwtVersion>
FF24

with setting to ListGrid setBodyOverflow(Overflow.AUTO) and trying to freeze some column --> It causes that the content of the column disapears.

Could you please have a look on it?

Cheers,
