Paul, the white-space:nowrap solved my main issue.
Back to the "fluid" top menu, I didn't see from your code how you accomplish that?
Before you respond, let me clarify some things... (And admit I'm not entirely sure what I want?!)
Like most things in life, my Main Menu Items will not all be the same (width). And I think it looks weird to have different spacing between things, e.g.
Home | News | Investing & Markets | Sports | World Events | Opinion
Admittedly I should strive to keep things similar width for aesthetics, but that isn't always possible.
So I figured that have a fluid Top Menu would help with that.
However, to further complicate things, I've got this fancy Min-Max Layout that you helped me created. So that means that my Top Menu cannot be wider than 760px in its narrowest incarnation. (I don't expect this to be an issue, though.)
I can probably just "Word Craft" - is that the term Rayzur uses? - my Main Menu Items and find a sensible fixed width, but who knows?!
For the Sub-menu, however, I do want/like the "wider than the parent look", because Sub-Menu Items by there more specific nature tend to be wider.
(If I can jet that "jog issue" fixed, I'm probably good for now, yet I've beenl "bitten by the fluid bug"!!)
