Clearing previous entries from field

In the sample functions post you describe a way for clearing cookies in Safari to return a browser to a known state.

I have a situation where, in a SUT running IE7, I have some previously entered data that may sometimes interfere with my scripting when it appears in a dropdown list from the field I am working with.

Is there a way that I can clear this buffer?

To wipe your personal data from IE7, click on the Tools menu and choose Delete Browsing History… Here you’re presented with buttons to delete your Temporary Internet Files (cache), cookies, history, saved form input, and stored passwords, or all at once.
