I just had this problem and came here to figure out what was going on and found this thread... I have almost all corsair hardware and sometimes Corsair Utility Engine sort of freezes. When this happens, your keyboard and mouse etc. still works, but "little things" stop working and you may not notice right away. Things like num lock and caps lock wont work, thumb buttons on the mouse and any macros or remaps stop working as well - Stuff the Corsair software is handling. It's happened several time
