parts move that i dont want to.

Hello,

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 :)
 
I found the problem.

The wall and the bar should be defined as Ground in bodies. and if any objects are moving together they should be defined as one body. and after doing so, every thing were right :)

Thanks for reading
