Hi All - Just converted from MM 6.1.2. This project was originally started on a version earlier than that. Anyhow, I do a right click on a bizobj to bring up the builder and I get the message file isclassinlibrary.prg does not exist. I know that function is now in the utility program but somewhere something is looking for it to be somewhere else I guess. Any thoughts as to what I need to change here. Thanks in advace. Tom
