How did my tabs on iGoogle manage to end up on the left side instead of on top?

I woke up this morning and my tabs were all on the left side of the page. Someone in the house might have done that accidentally, I don't know -- but how do I get them back to the default position?|||You can't move it back--Google changed the layout of the iGoogle page.|||just click and hold the tab bar and drag it to the side of the screen you want it
