[v6 General Discussion] PowerPoint Thumbnails

I just upgraded to build1.9. We did have this working most of the time in the last build but now when we load in our PowerPoint files, the thumbnails are all blank once again. Is anyone else experiencing this?

No problems loading PowerPoint using EW6.1.9 with PowerPoint 2013 (32-bit.) Also tried PowerPoint Viewer and it worked also.
If we load the PowerPoint file first before anything else is in the schedule, it works fine with correct thumbnails. If we add songs into the schedule and then add a PowerPoint, the thumbnails are blank. ????
If no difference adding PowerPoint to schedule that already contains songs.
In EasyWorship, click on edit, options, advanced and make sure that the option to use PowerPoint viewer is not checked.
