Projects can optionally be set to process automatically when a change is made that could affect the projects state. When starting a project as soon as the minimum requirements (see Minimums) are met, photos will orient automatically. The processing status icon on the status bar (see Status Bars) will briefly change to show that processing is taking place, and once done, the icon will revert to the ‘running’ icon.
As a project grows and processing starts to take more time a message will appear asking if you would like to switch off automatic processing. Once turned off, you must manually process the project by using the Process tool.
Automatic processing can be turned on or off by clicking the status bar processing icon or on the Project Information dialog box.

icon looks like this: 
When disabled the status bar icon looks
