Adam, I am not asking how to set the timer value. I'm reporting that the timer value is ignored. I have set timer values on each page to values that are other than 5 seconds. On playback, it matters not whether the value is 1, 7, 10, 10:00 -- whatever. The cue is played as if each page was set at 5 seconds.
Thank you for your suggestion to review the Playback Mode. I confirmed that it is set to normal.
Your statement to use the pull-down menu at the top-right of the cue (which didn't match what I was seeing) led me to the discovery that there are two methods of inserting slideshows. I incorrectly used the term "importing a PowerPoint" when I should have said "inserting a slideshow". I'm not sure what the differences are intended to be, but my bug report is relative to Insert / Slideshow, not Insert / Import Slideshow.
The Import Slideshow cue plays each slide according to the timing set.
The version is 6.3.80.
