PNG files turn solid black

[Beckylouwho]

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?

Hi @Beckylouwho - Is this all happening inside Windows Explorer? Have you played around with the View Tab? Perhaps set it to Large Icons, extra large icons etc...?
