We had a favicon previously that worked fine in all browswers, including IE. I recently deleted it and uploaded a new one. The new one works in Firefox and Safari. In IE, the old one still appears when I navigate between certain pages. Other times, the general IE "e" shows. I've cleared the Concrete5 cache, and browser caches.

What's the problem? Where's the new favicon in IE? Why is the old one still appearing sometimes?
