If you mossy your way over to the iGoogle Help Forum today, you may notice a bunch of threads complaining about how Google removed the top tabs from iGoogle and is forcing users to use the left hand navigation tabs.
Actually, this news is somewhat old. Back in June, many folks complained that they wanted top iGoogle tabs over left tabs and we offered a way to get those. Then it rolled out to other countries in July. It seems like now everyone has to have the left hand tabs, no matter what override you tried in the past.

There is seriously about twenty different threads over the past couple days on this topic.
