You have no doubt forgotten me but have been very helpful in the past. I am a neurologist who does research in cognition and sleep medicine. I have used 3D Gamestudio with success in developing Choice reaction time programs. Might I have a copy of reactiontest.c to review? I am sure you have some ideas which would be helpful to me.

I have just completed a program based on the article you referenced.

Thank you very much.
