that's weird

Check Library 'cleans' the library database and checks to see if the library database content is in synch with the library author and book folders and format files.

The viewer is a separate executable (ebook-viewer.exe) that doesn't need a library, e.g. I can run it and open a book format file that's on my desktop, in my downloads folder etc.

I don't understand why removing 'crud' from a calibre library database should have any impact on the performance of the viewer.
