**System Information**
Windows 7 Professional, Service Pack 1
Graphics card: GTX650
**Blender Version**
Broken: 2.74
Worked: None known. (The problem is with a new operator.)
**Short description of error**
When the bpy.ops.particle.copy_particle_systems operator is called using a Python script or a Python command entered in the console, it always copies all particle systems to the target even if it's called with "use_active=True".
The problem only seems to happen when the operator is called by Python commands in a script or a command entered in the console. The particle-panel's "Copy active to selected objects" menu item copies just the selected system as expected.
**Exact steps for others to reproduce the error**
Load the default file and switch the workspace to Scripting.
In Object mode, select the default cube and duplicate it with Shift-D.
Select the original cube and add two particle systems to it.
Select the copy cube, and shift-select the original cube.
In the console window, type or paste the line following line and press Enter:
bpy.ops.particle.copy_particle_systems(remove_target_particles=False, use_active=True)
The copy cube will now hold copies of both particle systems rather than just the system selected on the original cube.
