I have just created my first animation....considering the fact that I have been using Xara since X1, you may have deduced that I am a slow learner. Anyway just two simple questions.

1) I am working and improving on this animation but if I want to save it and come back to it later, what format should I save it as so that I can pick up where I left off?

2) This one is driving me crazy! After I created my work of art, I have moved the 'center of rotation' for each segment to create somewhat fluid motion. However, I cannot get the new center of rotation to stay where I put it. Each time I select a segment, the center is back in the middle or worse, somewhere else on the screen where I might have been working on it. Please tell me how to correct this.

Thank you,

Bob
