I'd be curious to know what browser he is running.
I don't let Netscape touch my computer, but I did run IE and Opera on it, trying to see if I could get it to erase my data. No luck.
Note to Bob: But I did notice, that in Opera, when the ad reloads itself, it changes the address bar to /ad.htm. Maybe Netscape does the same. I can see where that could really mess with data after refreshing the whole page.
