Combo in Grid problem version 2.0.2 in FireFox

I am trying to apply the upgrade to my grid. Works great in IE. The combo in the grid however does not function to expectations.

myCombo1 = new AW.Templates.Combo;
    myCombo2 = new AW.Templates.Combo;
    myCombo3 = new AW.Templates.Combo;
    myCombo4 = new AW.Templates.Combo;
    obj.setCellTemplate(myCombo1, 5);
    obj.setCellTemplate(myCombo2, 6);
    obj.setCellTemplate(myCombo3, 14);
    obj.setCellTemplate(myCombo4, 19);

obj.defineRowProperty("Mybackcolor", function(row){
        var list3 = new AW.UI.List;
        zone=this.getCellValue(24, row);
        if(obj.getCellValue(21, row)==0){

            obj.setPopupTemplate(list1, 5, row);
            e=0;
            for(i=0;i<exceptions.length;i++){
                if(obj.getCellValue(3, row)==exceptions[i]){
                    e=1;
                }
            }
            if(e!=1){
                obj.setPopupTemplate(list2, 6, row);
            }
            obj.setPopupTemplate(list4, 19);
            
        }

        if(zone!="0"){
            azones=zone.split(",");
            list3.setItemText(azones);
    		list3.setItemCount(azones.length);
            obj.setPopupTemplate(list3, 14, row);
        }
        
    	return this.getCellValue(22, row);
    });

In FF when a new selection is made it does not show on the cell. any typing in that cell also does not show visually. The functionality is still working, in that the server is still updated with the new values, but the visual change on the cell .. It seems like the css for the dropdown widget should be showing up transparent so that the actual cellText is visible, but in FF that does not appear to be happening.
