Sorry if wrong forum, couldn't see 4nt8...I've just started running win 10 (was running xp!!) home and installed 4nt8. All my cmd files work fine except that keystack does not work (works fine on xp & win 7) - says 'cannot install hook'. Guess this is a 4nt problem with win 10. Tried tcc/le download and of course it works fine. Anyone know why? Any idea on fix/workaround?
