jQuery Grid Plugin - jqGrid

I am trying to use cell editing with a check box. The issue is if the checkbox was previously checked "Yes" and I try to change it to No (unchecked), then use then mouse to click another cell the value does not get saved to "No" ie unchecked. If I use the tab key to move to the next cell everything works OK since saveCell() is called instead of editCell(). If I do the same operation and the value was previously unchecked then changing to checked and clicking on a different cell does save the checked (Yes) value successfully.

The difference is in editCell: the lines:

var vl = $("td:eq("+$t.p.savedRow[0].ic+")>#"+$t.p.savedRow[0].id+"_"+$t.p.savedRow[0].name,$t.rows[$t.p.savedRow[0].id]).val();
                if ($t.p.savedRow[0].v !=  vl) {
                    // save it
                    $($t).saveCell($t.p.savedRow[0].id,$t.p.savedRow[0].ic)
                } else {
                    // restore it
                    $($t).restoreCell($t.p.savedRow[0].id,$t.p.savedRow[0].ic);
                }

The value for vl for the 'yes' -> 'no' case is 'yes' instead of 'no'. Thus when comparing it to the saveCell value, it is the same so it restores it.  In the 'no' -> 'yes' case the two values are different this saveCell is called.

I tried both the 3.4.1 and 3.3.2 version with same result. I am also using 'clientArray'.
