From what I can tell, keyclone will hang when the traffic is ridiculously high. I use Ergodex keymaps so it might burst 7 keys is 150 milliseconds... so if I accidentally hit 3 ergodex buttons it might burst 21 in 150 MS. From what I can tell, "performance boost" makes the hangup a bit more rare. I think the big deal is to put delays between your keypresses or even use a manual keyboard. Works fine now! Thanks for the help last night
