Thank you a lot, it helped.
However, I also have a graphics-related question. My screenshots from Telwynium 1 and 2 are in 640x400 px size, but when I play book 3, I can't set the resolution to anything lower than 1176x664... Why and what can I do about it, so that I could have screenshots from each game in the same resolution?
I'll keep waiting for part 4, and when it's out, I'll want to play all four, because honestly I don't remember the whole story too well anymore...
