Jquery tab spinner does not stop in IE

Question

I have added spinner for jquery tab widget. It works fine on firefox, chrome and safari.

Only in IE when I click on the tab spinner starts and continues to spin even when data is loaded.

$("#mainTabContainer").tabs({ selected: tabIndex, 
                              spinner: spinnerImage, 
                              cache: true, 
                              select: fixTabAbort});

Any help appreciated.

Thanks
