I use ZONE2 feature of my 990 to run the speakers connected to the other rooms of my house (master bath, master bedroom, kitchen, garage). One thing that is annoying is that the ZONE2 remote does not make the 990 display turn on and show you that it received your button press. I have to first hit something on the main remote, like "volume up" button, to activate the 990 display. Then, if I hurry up and press a button on the ZONE2 remote, the display will indicate what ZONE2 key funciton was pressed. I consider this a bug in the software. Can it eventually be fixed in future firmware upgrade?
