/* ========================================== 
Notes:
[1] centers for IE5 Win, which happily ignores 'margin: auto' 
[2] no effect in Opera 7.54 Win, which wants a value for width
[3] fixes IE Win 'float/margin double-width bug' (should be: 'display: block')	
[4] shifts it out of view, since 'background-image: none' here breaks IE Win
[5] a twist on Dwyer image replacement (height: 0), that works correctly in IE5.5 Win. really should trademark this :)
[6] improves alignment in IE Win
[7] main col is 1px wider, and spacer 1px narrower than expected - prevents third column dropping in IE5 Mac
[8] avoiding padding on the list item containing a link prevents a nasty IE5 PC bug, in which content mysteriously 'drops' down the screen on mouseover. Padding is reapplied for the selected (non-linked) navigation item to make space for the list bullet to the left.
[9] this wrapper with reduced width prevents content overflow in IE5 Mac
