In Keynote 6.2, when hooked up to a VGA projection system, the first embedded video I try to play causes Keynote to freeze. After a restart (mb pro retina) it works fine. Thoughts?
Embedded videos in Keynote 6.2 play fine in office. But when I hook the MB up to a VGA projection system, the first video I try to play results in a complete freeze of Keynote. Requires force quit and restart of MB. Upon restart, all works perfectly. Why does it crash on the first attempt? Note, these Keynote files were orginally created in past versions of Keynote and have all been "upgraded" to Keynote 6.2. So all the videos existed (and worked perfectly) until the upgrade to 6.2. Thoughts?
