Gary, 1) Please send me your simple test project (source files) with 3 slides and no music where you also see this problem. Please use highly different images (colors) to make sure that we really see first slide. 2) As I understood flipping to first slide happens after 23-90 seconds after last slide was shown on the screen? 3) When the first slide suddenly appears - it stayed on the screen for all time or disappears quickly like a flash? 4) The first slide has transition effect - when first slide appears after last slide - what time point do you observe - at beginning of transition effect or at the end of transition effect? 5) What version of Windows you have intalled where the problem exists? Thank you in advance!
