Thanks...I seem to have it narrowed down to where it works consistently in FF, but not IE7, so at least I can focus on one thing now. I downloaded a generic ico file to use since I think some of the online apps that create ico files are little flaky.
That wiki article explains a lot. Google kept giving me conflicting info, but it's due to changes in the ways browsers handle favicons as new versions come out.
On a slight tangent, I found something interesting...I post it because it looked like fairly recent info: (link was very slow to load for me).
