Hi Gary and Acorn, I'm happy to your answers.

I tried the suggests and I obtain the result you can see under. At this time I cannot give the result with the MouseDown layer and I only match the color of MouseOver and Off.
But this workaround is good now but give me no really satisfaction so I think an another solution, If I make a primary bar in the index page with only the three firsts buttons and a secondary bar for the second page and next pages with the three first buttons and the another I think it's better.
I will try this and make a review.
