Thanks for the help first.
Great utility this script in http://www.dynamicdrive.com/dynamici...enu-glossy.htm, and I studied it and decide applied in one case study using images with corners, but I find some effect with the mouse events. When i change the corners in the images show the transparent background, note the effect in the corners with the others options, I try to change background, change positions, alternate div, change css sequences. If anyone can contribute I appreciate the help. I leave the archive of the modified menu for those interested.
