Thsnks for the reply Sergey.

Run this code snippet and let me know what you think

=========================
Public oFormRef As Object

m.oFormRef = CreateObject( [FirstLevelSubclass] )
With m.oFormRef

.Caption = [Instance of First Level Subclass with AutoCenter False]
.Width = Len(.Caption)*Fontmetric(6)
.AutoCenter = .F.
.Show()

EndWith && This

Return .T.

Define Class FirstLevelSubclass AS MyHighestFormClass

* AutoCenter is not changed from default
Name = [FirstLevelSubclass]

EndDefine

Define Class MyHighestFormClass AS Form

Name = [Myhighestformclass]
AutoCenter = .T.

EndDefine
