OK. Here is the scoop. This is not a bug. You can't reference this.parent in the Destory method of an object that has been removed. Make the following changed the program to make this work properly...

* in the KillItems procedure, change to use...

PROCEDURE KillItems
_SCREEN.Menu.Tools.Add.Report.Release
_SCREEN.Menu.Tools.Add.Remove.Release


* in the SubDemo class, change to use...

PROCEDURE Destroy
? "KILL " + THIS.Name
ENDPROC

PROCEDURE Release
? "RELEASE " + THIS.Name
THIS.Parent.Children = THIS.Parent.Children - 1
THIS.Parent.RemoveObject(THIS.Name)
ENDPROC
