I have 2 issues with the current experiment I am running. Firstly, MediaLab has a tendency to crash directly following a Voice Response item (not all times, but a high % of occasions).

Secondly, I have a large .WAV (c. 125MB) file embedded as a BackSound whilst an Image File is displayed in a later part of the same experiment. On occasions, this .WAV file simply does not get played back (c. 30% of occasions).

Can anyone shed any light, please? Many thanks!
