ioshtmlviewer auto-deactivation

I’m running a long read of a lot of data from a slow device. After ~75 seconds, the current window automatically throws a deactivate event, and I have no idea why this is happening.

This occurs in the simulator, iPhone and iPad hardware. Using 2017r2.1 for iOS 9.3 backward compatibility.

Any ideas of how to trace this?

TIA

Maybe the device is running out of memory.
Do you have any code in App.LowMemory event to warn you about this ?

I don’t, but at a total of ~20K of data, I think we’re well within the memory bounds of the devices.

…and our simulator effectively has infinite memory, within the 32-bit limits of the older versions.

There are no new window, timer or list events; it would be useful to be able to trace the source of an event, but I’m limited up to the event call itself.
