Hi there!
What is exactly the problem you are having? Are the buttons not rendering, are they too big, too small, do they not link to the right place?
The more information you are able to provide the better we can assist. What have you tried to fix this?
Thank you for your reply
The website renders the same in all browsers but when you click on “produtos” button for instance, it takes you down the page to the “produtos” section of the page, as in my customer’s PC running IE 6 or 7 when you click in that same button in the nav-Menu it works the same (works the same – meaning: renders fine, takes you to the correct url-{in this case – http://www.ortosilicone.com/#produtos}) but it doesnt scroll down to the “produtos” section of the page.
