So in my setup I have the primiary main PC controlling two NUCbox's which are secondary KVM machines. Both the secondary machines have mice attached and keypads and have all firewalls turned off, part of the private network (wired not wireless), fake pointer turned off and bat file run on all PC's.

Last night I was on fine using all 3 computers with no problems. This morning oen of the secondary machines when you connect via KVM the mouse becomes jittery and you cannot click on anything nor use the keyboard. The other secondary machine has no problems what so ever. I have done a fresh install, update, tested removing the mice, keypads etc, nothing seems to work.

Any suggestions for the next step?
