I am animating elements in motion and I run in to this problem:
When I try to create a key frame in the properties tab the key frame is added a frame or more to the right in the time line. When I try to move the key frame [on the time line] to the position I want and then try to modify the element it allows me to modify the element but the key frame properties are not changed.
(I am trying to explain this the best way I can)
