In Win 98 I enabled Thumbnail Views for my Adobe image files. I also turned on the "View as Web Page" option. I know Thumbnail is not allowed in Web Page mode, but I'd heard this setting would allow me to click on a file and see a mini-version of it in the Explorer window margin. This feature worked like a charm, but briefly. Since re-booting, this lovely trick no longer works. I've tried finagling the View/options/file settings, but nothing I do brings it back. What happened?
