Looks like I have Feb 2003 also, since I see it in C:\Program Files\Microsoft SDK\ReadMe.Htm. But is there an easy way to tell which SDK I actually am using?

Strange.. It is a bug so it will be fixed in the next release, but I just find it strange that it works for me and not for you. Which SDK are you using? I am using Feb 2003.
