Scripted client testing isn't a panacea. A while back we had a similar IE6-only issue which thankfully lasted only a day before we noticed the metric dip.
A push button was, in IE6 only, positioned behind an image with a higher z-index. The (Watir) automated test worked fine, because the button was there and a scripted event could hit it. But human users couldn't see it.
