Perhaps someone here can lend a hand with this small issue I am having with this site in Opera and IE. The site looks as it should in Safari, Firefox and Chrome but in Opera 10.5 and IE 8, the button labeled "CONTACTO" in the top navigation moves down a little bit and creates a gap between the navigation and the main banner that shouldn't be there.
It is odd as both the XHTML and CSS validate and there are no problems that I could discern.
Here is the link to the site: http://bit.ly/cHsJU9
Here is the link to the CSS file: http://bit.ly/9Ecuw7
I am also attaching the screenshots showing the problem and the site as it should look.
Any help would be greatly appreciated.
