You're welcome! I always try to leave good comments on game I truly like. And I have screenshots of the green boxes, but not of the flashing text. When I play through the demo again (because I totally will) I'll try to capture that. I can give you the screenshots I have when I come back from work.
I played this game on my 2014-bought desktop. :P It runs windows 8. I had many other things open at the time (Chrome, various programs, etc) so it's possible they conflicted. Or maybe the game works best when other programs are closed.
Edit: Some screenshots.
