Hi.
Vnc remoter seems to disconnect when the iPad is put into standby. Now I'm pretty sure that this didn't happen prior to iOS 5. I'm not sure if I have also done something in Remoter settings, although I can't see anything apart from Reconnect when disconnection is lost, which just reconnects automatically.
I'm sure it never used to lose connection.
I'm using the latest Remoter VNC. iPAD is running iOS 5.0.1. My mac mini is running Snow Leopard 10.6.8
Cheers.
