Hi, Thank you, Aragon. Actually, your patch does the same as mine (but in a different way). Thus we have at least 2 cases so far when the challenge is appeared. But I'm not sure if our solutions are the best way out. And... I believe, that it would be wonderful if Nate Lawson take a look here and evaluate the things we are talking through.
