Your oApp objects are different, but they may have properties that refer to the same object. For example, if your oApp has an oConnection property, (oProcess.oApp Is App.oApp) might return false whereas (oProcess.oApp.oConnection Is App.oApp.oConnection) could still return true. To make sure all of your reference properties are cloned and not referring to the same instance, you will need to do a deep copy.
