Hi - I have a medialab experiment file that calls a PowerPoint PPS file with an embedded macro (monitoring participants progress through a training tutorial and allowing or restricting them access to content according to path taken). When I run it with MediaLab there are no problems (the macro works perfectly); however, after the last slide a pop-up window asks me whether or not I want to save changes made to file, even though no changes were made.

How can I prevent that window from poping-up? Is this an issue with Medialab or PowerPoint?

Thanks!
