Hello Denise - Welcome to the Sony Forums 
Intelligent Auto issues aside, it may have something to do with the way that the Focus has been set up on the camera. The various modes available within the Focus menu on the camera are explained in the online user guide here:

You may find this easier to navigate than the regular manual.
If it is constantly moving to different areas and not giving the desired results, you may find that having it set to 'Center AF' will give you better quality images as the camera will have a set point to focus on which should enable you to compose your shots accordingly.
Hope this helps,
Simon
