Why does IE7 do this
when all the other browsers do this
Firefox Gran Paradiso (20081027 nightly)
Firefox 3.0.2 (Linux)
Opera 9.61 (Linux)
Google Chrome 0.2.149.30
This turns out to be a problem with IE that goes all the way back to IE6 and apparently doesn't seem to have been corrected with IE7. Just Google "css z-index ie" and you'll find a bunch of stuff on it. I'm already using a
z-index: 1; CSS property to get the menu to display on top of everything else. Still no joy with IE.
