HMMmmm - I *do* wander off this site to about 6 other commercial-type sites - weather.com, Drudgereport, etc. , I wonder if somehow a DELAYED popup can be riding on one of those that displays a while later? I *always* have my Zonealarm firewall engaged, usually even on THIS site. I tried the pointer you pointed me to, loaded the program and update, ran it, and other than a few cookies. no dangerous stuff...
