I get a crash every now and then on i. It usually happens when i use mute... Sometimes it happens right away and some times has to be on mute for a little while. Using windows vista and the mute button is the default pause button. When i get the crash a windows window opens saying that program is not responding and needs to be closed. When i click "ok" keyclone closes, but my wow instances are still up but key are not passed (i know they are not passed because keyclone is not up). It only seems to happen as soon as i play (about 5-10 min into it) then i get the error. I close down my wows and rerun keyclone and don't have a problem.

I hope that this helps a little.
