Layer not staying on screen and automatically advancing to next slide

Hi - this is describing, almost exactly, a challenge I am having right now. Oddly, sometimes it runs fine when previewing Scene rather than Slide, but this isn't consistent.  And the "quick skip" to the next slide is always happening in Review.  The features of my course mirror all of the details of Avi's except that mine are drag-and-drop slides rather than text entry.  And I have two layers (correct and incorrect) set up according to outcome.  Both are behaving the same: flash appearance and skip to next slide.  (Slide Advances by User, Hide Slide Layer when Timeline Finishes is unchecked, only triggers to advance to next slide are the Continue buttons within the two slide layers.)

Has there been any further findings on this particular case, or should I go ahead send along the file (if someone's willing to have a look)?
