John, thanks for that tip. I will look into Anyfile. Because of Lightroom, I don't use un-maximized PSD files anymore, but it was a frustrating task when I couldn't use Photoshop Lightroom to help me find certain Photoshop files. But, with time and therapy, I've gotten over it.
And, Peter: I'm not after small thumbnails so much as the ability to make a long page of regular sized ones. I guess the priority for Lightroom's design is to avoid scrolling by the viewer. Me, I'd rather have them scroll.
