Here's a bug I found while trying to create movements for a group of objects at once. To duplicate this:

1. Create an active object and clone it so there is a 5 by 5 grid of actives.

2. Select all of the objects with control+A or clicking and dragging over all of them.

3. In the properties window, go to the third tab, which is movement.

4. Click on the top section that says movement with a combo box and click the +/- button.

5. Click the dotted box at the right of this new window to create a new movement and then exit out of that window.

6. Back in the properties window, the movement combo box should be blank. Click the box and select movement number 2.

7. Set that to a pinball movement and start the application.

8. You should notice that every active falls except the first one. This is because all of the others have pinball movement as #1 except the first one, despite editing them all at once. This means that the only one that is set correctly is the first active.

I am on build 248 MMF2.
Note: The amount of actives you create doesn't matter, I only chose 5 by 5 to clearly show the problem.
