ill answer it anyways... 
Just make two same sized images, one for the background and one for the arrow
Ex: the size of the "area" is 150X40, then make two images that size.
The image for the arrow will have three states, just make the "hover" and "click" states the same.
Once the images have been assigned tweak the "left content margin" of the background so that the arrow will be covering all of the background - thus giving you either the hover efftec you want, or no hover effect at all
(all three states of the arrow = the same = no hover effect)
