Dave,
I don't know what Browser you are using but most of them have a place where you can clear the Temp. Internet Files, cookies, and history from the browser. If you want to go to the folders, you can use Explorer to get into them and clean them out.
Here is a link to the thread that I posted in at the FFR Coupe Forum.
