Hard to tell what's going on without seeing the full puppet rigging, but is yours set up the same way as the Walkbot example from the Start mode?
Is the arm in an independent group?
Is that group stapled to the body?
Are the wrist and elbow tagged handles on the arm group?
Is the arm one piece of artwork?
First, thanks for replying so soon.
After going over your check list, I noticed I had added a + symbol to my naming convention of the 'right hand' causing it to move 'independently'.
BTW, let give my highest praise for your demonstration videos, they are among the best in the industry both in content and delivery, Adobe is very very fortunate to have as an employee!
Again thank you for your excellent support and continued success.
