For a couple of weeks in any folder on my 2000 machine where I have the view set to "Thumbnail" it only displays the .bmps and has the default "this is a picture file" icon for .jpgs, .gifs, etc... If I select a .jpg or .gif it'll still showup in the preview pane to the left. No new software was installed and no confguration changes were made at the time that this started. Any ideas on how I can get the thumbnails back for all the common image types?
