I've been using Control for a remote focus unit for controlling theatre lights and I've noticed that it crashes pretty consistently. As long as I keep it on the screen it's fine, but when I switch applications and then switch back to Control it usually crashes as soon as I press a button in the interface I designed.
When it crashes I get dumped out to the iPhone's app selection screen and I can restart Control immediately but it has usually lost the destination from the list so I have to re-enter it, and then reselect the interface I was using. Once I do that it works fine, but if I switch apps again and then come back to Control it usually crashes again.
It seems to be related to having Control in the background for a significant period of time and then switching back to it. This is typical of lighting focus where I want to turn a light on and then spend a while adjusting it before moving on to another light and also when I'm busy with other things mixed in with focusing.
This leads me to a somewhat related question. Is there any way to code a destination into a interface? Or at the very least include a button on an interface that invokes Javascript to explicitly set a destination? I'm getting tired of having to keep going back to the Destinations screen to retype the address and reselect it. It would be nice if I could just go directly to the interface screen since I plan to always use this interface with the same destination.
