Ok.. this is weird. If I am in batch edit mode, and set the amount to edit at say 10 images, if I then try edit an image that is the album's 12th image, it goes into batch edit mode.
If I set the batch amount to say 80 images (the most I have in one album), then the single edit image will open the correct image, and not be in batch mode.
Single Image edit should work regardless or independent of the batch edit images at a time mode, I would think.
