For the pages that don't specify a font (like FR currently):
-Open the Internet Options under the Tools Menu
-Click on the Fonts button
-Set the font for the web page font
For pages that do specify a font (like FR about 6 o'clock), I can't find a way that IE 6 overrides it.
One more thing; try hitting Refresh while you hold the shift button; that should force a full reload of the page.
