Oldmariner,
I have the second one with the blue cover. One of the people commenting had the same problem I did with Evil Under the Sun.
"2) The cut scenes (the video sequences) for Evil Under The Sun are missing. The characters reference seeing something, the screen goes black, then fades back. No cut scene. How am I to solve a mystery if I don't get to see all of the content?"
I had XP when I played it. I might have to try it again on Win 7.
I'm almost certain I bought it direct from The Adventure Company. I certainly didn't order it from Amazon UK!

Gil.
