I have a running standalone (ensymbled) app on the phone. I switch to some othe app (e.g. fexplorer), then I come back to my app. When I try to exit I get the mentioned panic.
I test this issue on a really simple app now, like
My guess it has something to do with background / foreground switching, but I don't event know if there is some callback informing my app of the switch event?
import appuifw, e32
appuifw.app.exit_key_handler = exit_key_handler
appuifw.app.title = u'whatever'
appuifw.app.body = appuifw.Text()
app_lock = e32.Ao_lock()
Thanks very much for any possible interest
