Studio 13 course behaves erratically in Chrome; plus issues with .mov files
I have a new course which plays OK in Internet Explorer, and in Firefox. However it behaves unpredictably and erratically in Chrome (67). The couse comprises a number of silent .mov movies created on an iPad, linked to a menu system. Each movie has a separate audio file. Sometimes the movie fails to start but the audio plays; sometimes the movie plays but the audio doesn't; sometimes both play OK.
The movie files were created on an iPad and then edited on a PC using Quick Time pro. The movies play as required in Quick Time player, but when imported to Presenter they display start frames that had been cut from the movie.
