Infowindow scroll in Safari

Has anyone got the scroll to work in Safari with this trick? I get the
scroll working in Firefox and IE but not in Safari.

I use the following function, works in IE6 and FF:

function addDivHtml(html) {
html='<div style="width: 300px; height: 175px;
overflow:auto">'+html+'</div>';
return (html);

}

Sets infowindow to a specific size and if it is bigger than the
infowindow on the X or Y axis it will make scroll bars.

A while ago this message was posted on the group. It seems Google
groups will not let me reply to that thread, so I'm re-posting.
