Hovering over the menu "General Information" on http://apl.aip.org/ should open submenus. Works in FF+Opera, fails in Safari 3.1.1 and ToT.

ZIndex is the same as zIndex. The above code sets zIndex to -1 and the menu is hidden.
Confirmed with Safari 3.1.1 (5525.20) on Mac OS X 10.5.x (Leopard) and with WebKit nightly build r32698. Works on Firefox 2.0.0.x.

The bug seems to be in JSCSSStyleDeclarationCustom.cpp in cssPropertyName. The fix is in this line: name.append(toASCIILower(propertyName.data()[i++])); If we just remove the toASCIILower, that would fix the bug.
