Does Synergy or Input Director work with mouse movement in game? I use Microsoft Mouse Without Borders regularly with 2 PCs, even before trying to hardware box, and for 99% of what I use it for, it works fine. It does have a 4 PC limitation, so I am looking for an alternative.

With Mouse Without Borders, it doesn't seem to be able to "hold" the mouse button in a down position, it seems to just send one click and that's it, making looking around with right click or moving with both buttons held not functional.
