Earlier this evening I noticed the thumbnail icons in My Pictures folder, (both the image files and subfolders) were not displaying with their usual thumbnail clarity, but instead, pixelated in a way that suggested the system had altered their display, as opposed to a video or graphic issue. Opening other folders on my desktop to thumbnail icons that displayed with their normal clarity, reinforced this belief, as it seemed limited to only my system folders ( "My Pictures", "My Documents" ) having left any folders I created, unaffected. I remembered having changed the folder properties the other night, to show all hidden files, but never restoring them, so in an attempt to return things to their previous state, I clicked Do not show "Hidden files and folders", and my Documents Folder immediately went blank, along with my Pictures Folder. Currently, I've undone that once again, and all the files are now displaying, but all in semi-transparent, "unhidden" status. Any help would be highly appreciated.
