An error has occurred in the script on this page

Hi ,

When I click on search help on any field of any webdynpro ABAP application I am getting Error "An error has occurred in the script on this page", with message "Qbject doesn't support this property or method".

I reinstalled IE6 , it didnot worked, isntalled IE7 still not working. In other systems same applications are working fine in ie6 and ie7.

Thanks,
