I have installed Internet Explorer 7 RC1 on my WinXP box and found that the menus on this site didn’t work right with it. IE 7 now interprets child selectors. So the selector that was formally meant to be read by Firefox and Opera is now also read by IE. Unfortunately the
top:auto;left:auto statements are interpreted differently by IE 7.
So now I dropped the child selector and the auto-statements and now the menus look like they looked in IE 6 in all browsers. It’s not that bad. They overlap the menubar items a bit now, but that’s OK. At least it works on all major browsers now.
