Hi Peter, For that record that has a pptx file, do you see a generic
thumbnail, or do you see nothing?

I think if it can't create a thumbnail, then it puts up a generic
thumbnail.  You can go to the item that has the pptx file and select "Edit
Item" and see what it has for files.  If it creates a thumbnail it will
show up in the files tab.  See if that can give you a clue as to what is
happening.  It may be that for pptx, it can't create a thumbnail, or
creates an empty file.
