Is anyone else have this issues? I control all my AV stuff from an iPAD with HSTouch. The receiver simply becomes unresponsive after a while and then works again if I turn the plugin on/off.

I have an SR5012 and this was stable under HS3.

Extra point question...

Any idea why the Denon version (which seems to also work with my receiver but not the one I bought) has a toggle function under mute and this doesn't? Kind of a pain.
