Thanks SKO! I had already fiddled with that. But I followed your cue and dropped it down to "Accept ALL" and then relaunched IE (v 6.0.2900.2180), still no dice.
It's weird- I'm not having problems w/ any other websites and their cookies.
It goes to the login prompt whenever I click on My FT or OMNI from the main title bar. If I click OMNI from the main forum list, it's ok.
Am I S-O-L?
