Bsave dynamic blocks

Hi all,
I have been trying for hours to save the dynamic blocks I created in
block editor. I am creating a linear aray with a simple shape.
Creating works fine and after returning to the drawing editor the aray
works fine.
However when I want to use the newly created (or re-created) block in
a new drawing the block has lost all its dynamic parameters.
I have done this exercise before and had no problems. The blocks I
created weeks ago are still working fine with any new drawing.
I am at the end and need help. It seems that bsave does not save the
dynamic block. When I look in my block directory then the date and
time do reflect the time when I bsave-d the block but remain the date
and time when initially created. And yes my explorer is set to show
"last modified".
Any help will be greatly appreciated.
Thanks
Daniel
