I am using Paperscan 18.104.22.168 Home edition. When I scan multiple documents the thumbnails are blank and the preview pane is empty unless it is at 25% or larger. This did not occur until I began scanning multiple docs at one time. If I increase the zoom so I can only see a portion of the scan (preview pane only) at least it appears. If I click on Fit to Page, it disappears again from the preview pane.
Any ideas ?
