My files used to have the proper backgrounds, was this caused by some update from Microsoft? The thumbnails are black and when I click on the graphic it opens up solid black. I cannot use these files if I cannot see what they are! I use an alternate program to view them, but it takes a long time to keep opening each graphic to find the one I want in another program. How do I get my white backgrounds back on the thumbnails, and the transparent background back with other programs? I have way too many graphics I use to be opening each and every one in a separate program! Why has this changed and how do I get it to change back?
