I'm not sure its been fixed yet, but I've found that in order to turn off the screen and not stop playback, I had to install a "screenoff" cab, and open the specific application while playing a song.. this works but is kind of annoying.. a slightly better solution I've found is to use XDAShutdownv1.1 (Not sure about previous versions), and in menu set Sleep option to "Lights Out".. this way you can just hold down power button then press sleep while in groovefish (no menu surfing for other cab)... any fixes or other solutions are greatly welcome.. please let me know
