Disabling mouse over effect on EXT JS Grid header

Hi,



I am trying to disable the mouse over effect on EXT JS grid header.

I tried with following but it did not work

viewConfig: {

trackMouserOver : false

}

I am using extjs 4.1.3.

Here is my grid header:

Any help would be appreciated.

Thanks
