Thanks to Dave I got the top margin almost the same across browsers (rendering problem now, not a menu problem). Also stopped the followscroll until Andy can get a handle on that bug. I did manage to get a nice 1px gap (now desired, rather than the flush mode) between the photos and the menu consistent across browsers.

This is now RC10.
That's one-in-a-row...
