Flashing browser icon on Window Taskbar

hi, friends
I need to flash browser(IE) icon on window taskbar when browser is minimized or being cover by other application.
I read thru Google, but still cannot find the solution.
currently I am using
$.titleAlert("Alert", {                 requireBlur: false,                 stopOnFocus: false,                 duration: 10000,                 interval: 500             });
this one just changes browser title only, But cannot flash Browser icon on Taskbar.
I want to flash browser icon on window taskbar to notify user when new data comes in.
