Site menu looks good on all browsers on Windows but breaks on Mac OS

I've never ran into this problem before.

The menu looks good on Windows, but it breaks in Firefox, Chrome and Safari on Mac OS (saw this by using browsershots). I don't have access to a mac so I can't debug it properly. I think it might be cause by different letter 开发者_高级运维spacing or size. Does anyone have experience with this?

Thanks!

I'm viewing the site in firefox on a mac, and it looks like the div with id="wrapper" is not long enough to contain the menu.

Either increase div#wrapper to 960px:

#wrapper {
margin:0 auto;
width:980px;
}

or decrease size of menu font to 16px:

#mainMenu ul li a {
background:url("images/bk_menu.gif") repeat-x scroll 0 0 transparent;
color:#175689;
display:inline-block;
font-size:16px;
height:30px;
overflow:hidden;
padding:16px 19px 0;
text-decoration:none;
}

As far as I can see, it looks fine in Safari 4, unless you post a screenshot. But it might be that you have <div id="top-links"> occurring twice: [Invalid]Markup Validation of clients.newblack.ro integra - W3C Markup Validator.
