Photoshop Elements :: Images Too Small To Edit

Something just  happened here. In the past, when I open any photo in Elements 10, the image would pretty much fill the space. the bottom edge of the picture would almost reach the bottom of the workspace...whether vertical or horizontal format. Then I would create a duplicate and hit either ctrl + 0 (zero) and the duplicate would be a nice large size. ( Double clicking on the little hand in the tool bar would also do the same trick).
 
Now , for some reason, the picture opens to maybe 60% of that size. It's way too small to work on comfortably. The duplicate is even smaller.  When I hit the ctrl + 0 ...nothing happens size remains the same. If I pull on lower right hand corner to enlarge...it only enlarges the ruler and frame. Picture itself remains same small size. How can I get that back? I tried a system restore. that did not work.
