Stu,



I am not 100% sure I understand your question with regards to moving characters but here is how I have my mice setup.
Mouse1: Main Mouse, control of main PC.

Mouse2: Wireless Mouse, linked to Four Recievers. Controls all 4 'clone PCs' at the same time.

Mouse 3-6: Individually Control each machine.



You needed to have 'enhanced pointer control' turned on all 4 PC's so that the pointer moves at the same rate. If one pointer wanders off or gets out of synch you push the mouse to the uppoer left/right etc of the screen and they all resync. I had some mouse software installed on one PC for awhile and its kind of fucked my mouse settings for that clone, so I recommend using the same brand of mouse and not using any 'mouse software' for the clones either.
