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?

Thanks,

Phil Gillis

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.  That is what the binary was built
with.
