Aren't favicons supposed to be displayed next to each URL in the IE7 History
drop down window?

When I click on the down arrow at the end of the IE7 address bar, all web
sites that I've visited are displayed, but the favicon for each site has been
replaced by the generic internet explorer blue 'E'.

NOTE: When I type a URL into the IE7 Address Bar, the favicon for the web
site is displayed properly. It only gets "replaced" in the IE History drop
down window.

Any suggestions, regarding how to fix ??? Or has the IE History drop down
window always displayed sites in this manner -- without the favicon ???

All favicons in my "Favorites" file are fine.
