Nope, no stuttering.

The first time, I made it to the first postcard when the game stopped responding to any keypresses. I had to alt-ctrl-del out. The second run I wanted to see if there was an esc-menu. There was, but there was no other way to exit or select something than pressing esc again, which returned me to a black screen. I can post a dxdiag if that is helpful to you.
For the rest, your game is nice, everything seems to talk and move smoothly. Keep up the good work!
