Mouse Movements Constrained to Perfectly Linear Motion

[ThomShook 0]

Hey there, bit of an odd issue here that I'm not even too sure how to describe. Basically, I'd been running Synergy 1 client on my OSX machine and server on my Win10 machine perfectly. A few changes in my setup made it a lot easier for me to run server on OSX and client on Win10, which is what I tried. It works *mostly*, but on the Win10 client, horizontal and vertical mouse movements are constrained completely to those axies. In other words, if I'm moving mostly horizontally I can't make minor adjustments up or  down without stopping the mouse completely, it's basically functioning like a crane game. Any ideas how this can be fixed? I'd really prefer not to go back to my Win10 machine being the client but that's looking like my best option right now.
