Thank you for bringing this up.

My apologies I could not followup on this. I have another version in my local
tree but could not post it as I was not sure if I solved the problem
correctly. I will
clean it up and post for feedback as soon as I can.

P.S: Due to serious personal/family health issues I am not able to
devote much time
on this with other professional commitments. I feel bad that I have
this unfinished task.
Just in last one year things have not been stable for me & my family
and still not getting :(

Best regards,
Pankaj
