use the override key. override stops keys from being passed... which works well when you are chatting.

by default, the override hotkey is PAUSE. you can set it via setup/override

you will also hear a tone when you enable override and another when you disable it. it will also give you an audio reminder every 20 seconds (by default). all that is configurable

btw... if you bought the license on your friends computer... you will need to transfer it to your home machine (licenses are tied to the cpu)... unless he wants one as well.

if you need to transfer it, just drop me a PM here, or an email to keyclone -at- solidice.com
