Server Mac OSX Sierra - Synergy 1.8.4 Client Win 10 - Synergy 1.8.4   I have been using Synergy for a year with no problems, this started yesterday, may be related to Sierra Update on my Server.   The mouse moves normally on the server. However, on the client, the mouse seems to move left and up at a rate that is twice as fast/far as it does down and to the left.   Thanks in advance.
