System Information
Windows 7 64bit 8GB RAM
nVidia 460gtx

Blender Version
Broken: 2.69 2328f94
Worked: 2.67

Short description of error
Duplicating a mesh plane with a biods particle system causes Blender interface to not work correctly.

Exact steps for others to reproduce the error
I have attached a BLEND file.
Open the file and you will see a plane selected.
Press Play and observe the particle animation.
Press SHIFT-D to duplicate the plane and you will notice that the typical action does not happen. Typically when you duplicate an object you can position it with the mouse. In this scene, however, you can see the coordinates moving in the lower right hand corner of the 3D view but the duplicate plane is no where in sight. So click to lock in your duplication/move and you will see that the new duplicate resides on top of the original. Now press GY to grab the duplicate along the Y axis and it will jump snap to another location. So click to accept that and press Play to view the duplicate boids particle system and the particles no longer play correctly. Not like the way the particles move before the duplicate.

Not only does this append with BOIDS, but also with object whose both options "Rigid Body" and "Force field" are applied.

Add a cube
In Blender Render, "Physics" panel, select both "Force field" and "Rigid body"
shft+D
=> The simulation is glitchy

I've commited potential fix at df72d3c. Do you guys mind double-checking BOIDS works fine? Also, can you please upload test files which demonstrates issues with foce fields and rigid bodies?

Seems the bug is fixed for me :)

Strangely enough, I don't manage to reproduce the same glitch with my "Forced" Rigid bodies any more... maybe I had an old particle system linked to them somehow ... ?

Thanks !!

I tried a recent build a with the test file I submitted and it does seem to be fixed as well.

Thanks!
