jQuery Grid Plugin - jqGrid

Hi Tony,

In my Tree Grid I have added a drop down box in one column.
As per my requirement formatter was not suitable for the same so I used CDATA to add the drop down to the tree grid column with defining its onChange function.

But in IE I am not able to select any value from drop down.I need to hold the drop down with mouse and then need to drag its value to select.Neither its onChange function catches the drop down select event.Still not able to select any value from drop down in the IE.

Whereas in firefox I can select the value by holding the mouse button and onChange event is also getting fired on the value selection.

Cell editing is "true" for the grid.
Is there any jqGrid functionality which stops the onChange event of select drop down for getting fired?

Is there any way I can call the onChange event on the Drop down and select the value of the drop down in a normal way?(As drop down is not droping without holding the mouse button-it sticks to the first-default value).

Thanks,
