Hi,
I can see there was discussion that this was a system wide problem that has evidently been fixed. It has not been fixed for me. I can't reply on the dropbox solution, and nothing allows me to scroll from picture to picture. I literally have to look at a picture then hit the return arrow to go back to my entire folder of photos, select another picture, look at it, and then go back again to the main folder to get yet another photo. I pay for premium dropbox and am seriously considering finding a different way to store my photos - this is crazy. Having to download the photos onto my computer so I can scroll from photo to photo completely negates the reason I signed up for Dropbox!
