My photo app has blanked out all of my photos to grey. The icon on the toolbar is also blanked out in grey. The photos still exist (I think) because they are all still represented in the same spaces in the same folders. It is just that it is a plain grey space. When I double click on a photo it goes to a viewer, but it is blank and the dots at the top do there eternal march across the top like they are lost forever. I don't think I have done anything recently with software. It is as if it happened out of the blue.
