on the top, right side of my screen has a space to type in anything i want to find out about. whenever i type in something, it's added to a dropdown list of all i've typed before with that beginning letter. i have tried to delete some of these items on the dropdown list and can't do it. what's the secret?? i have IE7. i clicked on an item on the list and it went to the google space highlighted then i rt. clicked on it, got a dropdown menu w/"delete" , clicked that, and the word was still on the danged list. now what??
