I created a favicon.ico file using one of the online favicon generators, placed it in the root of my site, and added this line of code to my pages:
	Code:
	<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />
 On one computer running XP, it shows up in Firefox, but not in IE7. On my laptop running Vista, I get the opposite...shows up in IE7 but not Firefox. 
I've tried clearing cache, and most of the obvious things, but I'm up against a brick wall. Any "Favicons for Dummies" type tutorials out there?
