If you moved the classlib out from under the forms and classlibs then you are going to have to go in and repair all of the classloc columns as appropriate (make at leaset two independent backups first). VFP is finding the bad parent classlib by relative path or explicit path during the build process because that's what you told it to do. If you really want to find the problem classes rename the classlib in s:\common30\libs this will caue the build process to throw errors because the file can no longer be found.
