Thought it was normal. Mine has a drop down menu to search other sites as well but seems to default to Google.
Using:
Firefox 2.0.0.7 & IE7

I recently did a Windows update on my Vista computer. Now there's a small Google search box in the top left corner of the screen. I can't figure out how to remove it. Help. Thanks.
