I have only just started using Keyclone a few days ago and I seem to be having the same problem.

I use 2 computers and have tried logging into wow and not touching anything and walking away, by the time i come back one keyclone has crashed(always the same computer). I use sysnergy at the same time and it seems to block synergy when it crashes, synergy will start responding after i have killed keyclone in the task manager.

Any idea's?
