eddiehellfire, Go to the link below and download previewfix.zip
Unzip it, double-click the .reg file, say yes to the prompt, restart your computer, and the problem should be corrected.
I save all my scanned/downloaded pictures into a desktop folder with "View As A Web Page" enabled. By moving my pointer (I have one-click enabled) over a file name, Windows generated a preview of the photo on the left side under the file description. This worked for both jpg and bmp files. Recently it stopped giving me a preview of the jpgs, tho it still previews bmps. I can preview them with "Quick View", but it sure was handier before. I've searched Win98 Help and at the MS web site, but found nothing. And ideas?
