How do I clear the casch?
Tools->Options->Advanced. In the Cached Web Content section, press “Clear Now”.
By the way, in some other situations, if that isn’t enough, you’d clear Daz cookies. Tools->Options->Privacy remove individual cookies - type “Daz” into the search box, ctrl-shift highlight the ones which are actually Daz, and hit the delete. (Mac users use that button that they have instead of the control key).
In Internet Explorer:
Tools->Internet Options->General, in Browsing history click delete (that wipes out cache, cookies, history, saved passwords, and web form information - which seems drastic).
