Why you are using IE?, don't you know that IE is the worst browser?
If you DO have fire fox (or any other "good" browser) and you don't have any problems with it, then, Why you don't just use it and forgot about IE.
I don't have any problems with the search bar, are you sure that it don't work for you?, or you are saying that you don't know how to use it?
honestly, I don't understand what is your problem.
Do you have the same problem with any other browser?, other than IE (I know that you already try-ed fire fox). Opera, Avant, google chrome, etc.?
