After completing the processing procedure, the application can be closed or minimized to tray. Such behaviour is regulated with the Close after processing and Hide to tray instead of close settings. The settings are located on the File main menu > Options > Explorer tab.
If the Close after processing option is enabled, inPhoto ID PS completes the work after processing. Whether the application to be closed or to be minimized to tray depends on the Hide to tray instead of close setting.
The active Hide to tray instead of close setting changes closing inPhoto ID PS to minimization to tray.
