The Kings Quest IV copy protection sometimes asks for the fifth word in the first paragraph on the sixth page. This word is not listed on the copy protection sheet. I just thought I would mention this because it is a fairly annoying problem that could be pretty easily fixed by the GOG team.
cheers!

also double post because the post message button is broken....

Yeap, there are actually a few that it will ask you that aren't listed in the cheat sheet. For that particular one that you listed, the answer is beautiful

I only have these on Steam not GOG, but if the original manual isn't included, you can google it and look it up through there. The Steam version is the same way and I've had to do this a couple times.
