Except in Images all the thumbnails are solid black. I've tried refreshing thumbnails, changing icon displays, etc.
Dragging an image over a song in the Schedule does not update the thumbnail and its confusing. The image does show in the Preview.
What version and release of Easy Worship? What version of Windows? What graphics card are you using?
I am experiencing the same issue since I upgraded to version 22.214.171.124. Not all thumbnails are black, but the majority of them.
