CS6 - Generating Peak Files every time I open the same project?

[Stevedocmaker]

CS6 wants to generate peak files every time I open the same project.  I had a similar problem once with CS5, and when I unchecked the box telling the applicatio to save media files near their originals it went awat.  But this box is still unchecked, and yet PP keeps wasting time and processing with this task.  How can I get the program to recognize the Peak Files it has already created?
