Hi bob3160,
It better be, and that goes for all browsers, and software as such. Everything is being constantly developed, and you and me too I hope, for else we have abandoned ware, software or programs that the developer left. there would not be an IE 7.0 beta as IE new versions was not being developed, that is constantly re-developed. A program that ïs "as is" per definition is a "dangerous"program, and you will use "at your own risk". I type this on a fully patched, fully updated XP professional with SP2 in a fully patched IE browser, still Bob, I am doing this "on my own risk", and at home I have FF with NoScript and ad-block, and self-made filters, anti-spoof check, plug-in link scanner, but there also I use this browser "at my own risk". Read these Eula's boy.
greets,
polonus
