DO not share foxuser.dbf between VFP7 and VFP9 or you may encounter strange problems.

VFP9 allows property values to exceed 255 charcters. Classes/Forms with such properties cannot be open in VFP7. In particular, watch out for _MemeberData property which is updated by Class/Form Designer implicitly.
