When using Options+ between 2 Windows PCs both with Flow enabled, I often have a hard time transitioning the mouse from one screen to another. It seems like it will "leave" the primary computer to the secondary one very easily but won't come back. After watching the Flow screen for some time, it appears as though the primary computer is reported as "disconnected" fairly frequently. This was not a problem with the original Options and I'm not sure what the cause is.
