Cute, Confirms my experience though. Conditional Formatting in Excel is a nightmare, they got me excited at first, but I wasted so much time and got so frustrated with them - I gave up and have never used them since. As the article says performance is abysmal in large spreadsheets, also they do not play well with Excel tables, (which I use a lot) you end up with thousands of CF formulas in tables, they keep breeding and mutating and you cant stop them!
