Hi Donald,
that happens if you added a property to a VFP 7 class that is now a native property in VFP 8. The storage format for those have changed making VFP think that a plain text in a user defined property now is an expression. That happens for HeaderClass, HeaderClassLibrary, StatusbarText, TooltipText, MemberClass, MemberClassLibrary, DEClass and DEClassLibrary.
