Yes! It is non-linear skb! All works! THANK YOU VERY MUCH!
I try to fix this bug for about 2 weeks. And You fix it for 15 minutes!
Non of my books tell me about non-linear skb. Google was useless!
Man, You are the best! :)
I want to give You a little present - bottle of Russian vodka (old Russian tradition :) ).
How can I pass it to You? Give me your address please!
