Avatar always returns in initial position

[pattie]

I have a problem I cannot figure out.
After I run a sequence on the male avatar provided by Worldviz, the avatar always returns in its initial posing position (standing with spreaded arms). For example, the sequence consists of walking to a position, then sitting. I would like the avatar to stay in the sitting position after the sequence has ended, but it will always return in its initial position.
I probably forgot something stupid :-)
Thanks for your help
