jpg thumbnails turn black
Folder with jpgs in them with thumbnail view, some thumbnails are black. If i cycle through the thumbnail size options, some more of the existing thumbnails turn black. If the images or folders are copied to another drive, it presents the same characteristic. chkdsk ok. I have disabled and deleted the swap file. cleared the thumbnail cache. turned on and off thunbnails in folder options and performance tab, and on and off in gpedit. The system has been rebooted without any startup items, but all services. I've reset the text size to 100%, down from medium. cleared all thumbnails with cleanmgr.
I am out of ideas. most strange is that sometimes you can click into a folder where thumbnails exist, and watch some...not all, of them turn black. the image itself is fine. most of the time the preview shows in the preview pane, but not in the status line of explorer.
this is win7 64. I've run out of things to try. i can rotate an image from the context menu, the thumbnail and statusnail will appear. if i rotate it back, it will turn black again. If i rotate and close, and then rotate and close again in the windows image viewer, the thumbnail is fine.
this is a pretty good mystery. any ideas anyone?
