Never saw this one coming. Microsoft's Internet Explorer 7.0, just officially released Wednesday, already has a security bug. According to the Register, the bug is a result of faulty code carried over from IE6. So if IE7 was supposed to be a rewrite, and it has IE6 bugs, what does that say about Vista, which is supposed to a complete rewrite as well? Will we see XP bugs showing up?
Eweek has written a fairly favorable review about IE7, that talks about some of the security features that are admittably an improvment. I think IE7 is certainly a worthy release (that's long overdue), but it doesn't make IE the best browser available.
