I have to turn off the corss system file copy because it constantly hangs my systems. I do a lot of file manipulation and am constantly copying files within a single system. Multiplicity starts preparing for a cross system copy even if I have no intention of copying the file cross system. Could you make it so it only copies the files over if I move my mouse back to the original system? Or perhaps an additional key sequence? Or when I actually do a paste on the target system? I'd love to have this feature work, I just can't afford the constant interruption as it tries to prep a 5gb copy that isn't ever going to the other system anyway.
