It appears the only BV menu bar that works properly with browsers other than IE (lets say with Firefox or Netscape, etc.) is Default. None of the "Theme" drop-downs will work properly...they'll be cut-off, hence inoperable for the most part.
It would be nice to have other options. Perfect example: click "Quick Links" at top of this page. I think it's using Default menu bar, but the drop-down is boxed, ala the Theme menus. Maybe there's a way to do this, but being a newbie, I don't know it. On my site, I modified the Theme Office .css file to accomodate my needs. But, as with all Theme menus, it doesn't work in Firefox.
Anyway, just a suggestion. Thanks!
