I had no issues with Presenter 8 (64 bit) running under Windows 10 Pro and MS PowerPoint 2016 (64 bit) Standalone. However, when I upgraded my Windows 10 with their latest release of Version 1703, it caused all types of issues within PowerPoint even when trying to save files (which froze and I ended up losing my changes. I wasn't even using Presenter with this slideshow other than it was running in the background. Two years ago I recently had to retire and didn't necessarily upgrade my Presenter 8 since it was functional for me. Has anyone experienced what I went thru this weekend and found an answer other than upgrading to Presenter 11 (but I'm not sure how that will work with MS's upgraded Windows 10 release of "Creator's Update" (since it appears P11 seems to have issues within it's own right currently).
