This happens about 100 times every night, and it's driving me a little crazy (a lot actually). To get rid of the cursor, she has to ask me to move my cursor into and out of the media center computer. When she moves her mouse into the media center computer and then moves it out, the media center's mouse cursor gets stuck on top of all applications (the video we're playing in VLC, Chrome, etc) in the center of the media center screen. We each have a computer, one mac, one windows 10, both set up with synergy as servers, and one media center computer (windows) set up as a client that connects to both servers. My wife and I share a media computer and we're both constantly accessing it. This bug is the single biggest annoyance of my day, every day. I've been waiting so long for a fix to this.
