>Does anyone know where I can get my hands on a patch to take VFP 3.0 to VFP3.0b? I've a client that requires it.

Phone Microsoft and order it. It is free (I think including shipping). If the operator can't find it or doesn't know what you are talking about, hang up and get a new rep. It took me a few tries (in Canada) to get someone to find the product. The patch ships only with the full product so you will need to provide proof that you own the copy over the phone.
