Thanks Jim,
Yes it should be on the T2 list.  I signed up but after many tries I
realized that I can't send any messages there for some tech reason.  So I
had to ask the our list, hoping it will pass since it is kind of the same
system there.
Your answers are great, thank you.  I think I have some rust or similar
thing that is restricting the movement.
