> no one saw it during the QA process because all the webdevs were using Macs, which have invisible scrollbars by default. We've had this happen numerous times in the past. As a result, I had to make it mandatory that devs on my team and the QA team have scrollbars always on on their Macs. They get frustrated that I require it but it catches so many minor layout issues that it's worth it.
