I have as well already reported that XnViewMP happens to "forget" all the thumbnails that have been already created and indexed while they are still in the database, they are no longer visible in browser view.
Maybe these 2 events are related as it just happend again and almost 45000 thumbnails have gone and need to be recreated.
What happend? Suddenly the browser view changed from thumbnails+filename to thumbnails & labels. And when I switched back to thumbnails and labels, all thumbnails were gone and it Xnview started to recreate them one by one.
