I'm having this strange problem with an horizontal scrollbar showing up in the redesign of a site. the only difference in the redesign is that instead of having an embedded flash movie as a navigation bar in my div id="layer3" I know have a text based navigation bar in that same div id="layer3"
This seems to only happen in IE 5 on a Mac and I can't seem to get rid of it.

Here is an example of both designs :

new one:


Any suggestions how I can get rid of this problem without using iframes ? thanks
