How do i make a link stay highlighted when its clicked

Hi,

This is a relatively simple question but i am quite annoyed not to have been able to figure this out.

I have 4 buttons - About Us, Products… etc.

I want a mouse over so that when i mouse over the About Us text, the text changes color and when i MouseOut, it goes back to the original color.

Also when the link is clicked and the page loads, I would like the link to stay highlighted so that the visitor knows which page he/she is on.

I have tried using movieclip with mouseover, mouseout states in individual keyframes. My actionscript states that on(press) gotoAndStop(mouseover) so that the link stays highlighted when the page loads but I also have an on(rollOut) which states that when I rolloff the link, the color should change back to the normal state. So how do i get this to work?

Thanks,
vazash.
