Cannot easily save jpeg after cropping CS6
Suddenly, if I open a bog standard jpeg, make a small change such as crop it, and then close down to save, I now have to jump through some hoops to do so.
Whereas before I could just press SAVE, and it would save, now I can't do that. The save box appears and the the jpeg option has disappeared from the drop down box (ie I only have the options shown in screengrab below), and I have to flatten the image and then save as jpeg.
To clarify, no layers have been added when I crop the image. (I understand that adding layers mean you have to flatten...)
It is a bit annoying, and I don't know why it has suddenly started doing this? Any help would be great.
