i will explain my problem the best i can. i have a wall, and bar is sticking out of it. in the end of it there is a hole, another bar is connected to that hole via pin connection.

Now i am trying to make an animation of that bar rotating around the first. i am using snapshots. in the model, the second bar was rotating fine. but when the animation started, the first bar moved ( the one that is sticking out of the wall and it shouldnt be moving ). i am a noob for this, and i need this urgently.

Please somebody help!! i appreciate it
