That shouldn't be necessary. Read '8 Pints' and Barbara's posts. Reducing the security level to medium also worked for me, though had Microsoft not screwed up again, no action would have been needed. I should steer clear of Mcafee if I were you.

The latest XP update (SP3 itself gave me no problems that I noticed) is also disabling my Wacom tablet drivers every time I boot up, but they can be turned back on again easily enough. Again, though, a properly written patch would have been checked for things like that.
