Is it b/w?
That's not what I read up top. The issue is well known and is well discussed. I can only guess that you were expecting a fix for what you have and having worked with folks over this one I have learned that many dig in all heels when you tell (and even show) them about using something else.
I see I have shared enough but you may need more time to read more and try more. I had hopes to shorten the usual learning cycle but have failed.
