Autoclose Window (w/Applescript)

Have a startup program that you need to close each time you boot / login?

Because I use a 3rd party USB wireless adapter on my G5, Leopard doesn't recognize the adapter without a 3rd party wireless program. That programs requires no interaction other than closing it. So I wrote the below Applescript to solve this.

delay6
tellapplication"System Events"totellprocess"Ralink Wireless Utility"
clickbutton1ofwindow1-- or window "Wireless Utility"
endtell
