 It's subtle, and seems to vary in intensity between both browsers and
 Windows / OS X, probably due to different hardware acceleration / anti-
 aliasing handling.

 On Windows, I can only see it on Firefox (tested with 7); IE9 and Chrome
 appear fine. A colleague can see it in Chrome and Firefox on OS X.
 Probably anti-aliasing differences between the OS's / browsers.

 Reducing shadow strength to 3px seems to fix it for me, but not sure if
 the aesthetic change is desirable. It's more complex, but we could also
 give the parent container's anchor a white background and z-index it above
 the submenu UL.
