A guy said his problem began after installing the software (which he has now uninstalled) that came with his new Canon camera. When he opens a folder of pictures (all jpgs) and his display default is set to "Thumbnails", he gets SMALL images (but not quite as small as "icons.") It also is VERY slow to display the images. If he changes the display to anything except thumbnail and then back to thumbnail, he gets the proper thumbnail size on all pics. If he just double clicks on the small image to open it and then closes it, all the images in the folder change to the correct thumbnail size. He has thousands of pictures to sort through and the extra steps are driving him crazy. Suggestions?
