Left column was completely filled with a blue background, right column with ads. Only after scrolling down till below the ads on the righ did the "top" ads show up and the natural results below that. "Best" of all: clicking the blue background led to the site of the first advertiser.
opera browser 6, w2k, multiple progs/windows open --> small window size, resolution 1024*768, font size 125% ("large").
I've seen it several times since but I can't reproduce the small new ad layout now in IE to test.
Tips:
- try half width window size.
- even if it only fails in Opera, at least make the "Sponsored links" unclickable or link to Google and not advertiser
