I have a primary PC and two secondary PC's. One of my secondary PC's is receiving what I type on the primary PC. The green border is on the primary PC when it happens. It didn't do this initially, just started about a week ago.
Primary is Win 10 Enterprise 1803 and the problematic secondary is Windows 10 Pro 1809. Multiplicity 3.44 KVM Pro build 00090.
Thanks for any suggestions.
