Button still active problem

hey guys

Promblem on my site:

http://www.new.designreel.com

“When you select an option in the portfolio section, the link you selected remains active when the content loads over it. Move the mouse pointer around over the white area to the left of the photo of the girl, you’ll see what I mean.”

I’m struggling to stop that happening - as the button that is causing the problem is within the sliding page - I can’t take the sliding page out of that section of the movie as if I do when the user closes the portfolio section the sliding page will slide back to the “about” section - instead of returning to the portfolio main section which there were at (sliding page portfolio section)

I tried another way which was to add a solid colour over where the buttons would be to block them on the layer above the sliding pages - but that didn’t work either

I have a feeling this is going to be a tricky one…hope somebody can help to solve this issue
