ListGrid sort in firefox

Hello,
I am facing a strange bug in firefox:

when I open any ListGridSample, like http://www.smartclient.com/smartgwt/showcase/#grid_appearance_columnorder, and start sorting the columns, soon the columns autofit its width AND stop sorting, actually, it takes two or three clicks to sort again or change sorting direction. See attachment.

The columns autofits its width no matter where I click (on the right or left corner of its header);

I don't face this issue in IE or Chrome.

Any clue?

Thanks in advance.
