Same here. I frequently downsize finished tif images and save a jpg version "as a copy." Every time I do this now, after saving "as a copy" the new jpg image shows at least twice (duplicates side by side) in the Adobe Bridge previews panel, and I can't open either image. The only remedy is to open another folder of images, then return to the previous folder, where the duplicates are now gone and I can once again open the jpg copy. Effectively, closing the current image folder and then re-opening it. Obviously, this shouldn't be happening.
This is still an issue with Beta 126.96.36.1996
