Hello there,

The entire experiment ran smoothly when I:

1) Saved the PowerPoint file as a .pps NOT a .ppt
2) Did not put the .pps file directly into the experiment, instead I saved the .pps file into a questionnaire and put that into the experiment

I hope that that helps some poor soul avoid what I've experienced for the past three weeks! Thanks for your help all along!

Be blessed!

Tina
