Hear.app audio events as MenuExtra SSB

Is there a reason why Fluid MenuExtra SSB's don't get recognized as a running application to "Hear"? http://www.joesoft.com/products/hear.php (essentially a iWow type app, for all system audio, not just iTunes) When ran as a normal application, the audio events work just fine, and as intended. I've also reported this to Joesoft, and awaiting a response.
