using

thisform.oMyClass2 = NEWOBJECT( "MyClass2", "MyClass2Lib.VCX")

thisform.oMyClass2 holds a reference to an object that is not a member of the form

To make it a member you need to use .addObject() instead:

thisform.addObject('oMyClass2', "MyClass2")

you need this earlier:

set classlib to MyClass2Lib additive
