Hello, 
I am trying to create my own character.  I've got it set up.  I used the "Ted" character and simply replaced the sprites (although I do have the pipeline edition)

However, some of my bones are now gray, and I can't figure out how to make them work again.  I have tried "connect" and it will not connect the bones - possibly because they're already connected?  
I tried to find the answers online and in this forum and in the CA4 manual, and found some references to bones being "active" but if you can see the image I'm including, all of them appear to be active and do nothing when I click the button.  I'm stumped!
