Persisting Stream Buffer Handling Mode

Is it possible to persist the Stream Buffer Handling Mode when using SpinView? I attempted to do this by setting the mode I wanted ("Oldest First") in the Features > Stream Parameters > Buffer Handling Control for each camera, and then saving the current settings to the UserSet1, but when I reset a device I always get this message:

LOG_LEVEL_NOTICE   SpinnakerNETGUI    SpinView.SpinView_WPF    Device Stream Buffer Handling Mode set to "Newest Only"    

How can I prevent that from happening?

  No, it is not possible.  The Stream Buffer Handling Mode default value is determined by the application; for SpinView, its NewestOnly.  The buffer handling mode is within the Stream Parameters nodemap, not the camera nodemap, which is why saving to UserSet doesn't work.  You would need to manually change this value, along with any other value change you want in the Stream Parameters nodemap, each time you run SpinView

  That's unfortunate, but thank you for your response.
