Thanks for letting me know about this. If it still happens with the
latest version, could you possibly send me the logcat output?

Sorry, I was messing around with auto-focus - it should be less fiddly
now (though still far from perfect, especially on phones without macro
focus).

Your opinion would be a bargain at twice the price. ;-)

I agree that the experience is still too fiddly and unreliable for
production use. The only thing I'd say in its favour is that it's less
bad than the other methods I've tried. If you write a proof-of-concept
for a better method then I'll steal it without a moment's hesitation.

Cheers,
