In the browser settings I accidentally typed the wrong startup URL. Now I don't know how to change the damn thing.

I'm guessing there should be some hover-over behavior that when I select the URL in question an "X" will show up that lets me make the change, but I can't get it to show up and I can't find anyway to remove it. It's possible I'm being dense.

I tried removing the user and re-adding, but the setting was back there when I added them back.

I tried re-installing Chromium OS, it was still there. So I'm guess the association between this account and this incorrect startup URL is stored on "the cloud".

Does anyone know how this can be changed?

If I wanted to use the Guest account instead of using a real account for this, is it possible as owner to set default guest policies such as the default home page?
