Not sure what you mean? What would you like the app to do in such cases?
It would be best if the app silently failed and didn't add a new error entry to the media list. If the model is in a long private, it's easy for the list to fill up with errors otherwise.
That is, this would be good when MFC is working again. See related post from today.
When a MyFreeCams model is in a private session, a monitor for her URL returns a 404 (Not Found) error. Is there a way to suppress this error?
