Here is my setup:

1 desktop for my main
1 laptopn for my 4 clones

When I press pause on my desktop to chat with someone, keyclone on the laptop will crash (not everytime but 20-30% of the time).
I kill it and restart it, reconnect with the desktop and it's all good.

Note: To connect the 2 keyclones, I use the connect feature from the laptop with my desktop ip address.

Tell me if you need more information or need me to do any test.
