It is possible to create a default C2A configuration to which you can roll back very quickly using for instance a keyboard shortcut. You can save a default configuration using the command Save default configuration from the File menu. All the parameters will be saved in the default configuration except: paths to databases, displayed help bubbles, the Welcome window, the positions and sizes of windows, displayed icons on the main toolbar, automatic placement of the object information window. The key combination Ctrl+End is a shortcut to accelerate the default configuration saving.
Once a default configuration is defined, you can quickly load the default configuration using the command Load default configuration from the File menu. The key combination Ctrl+End is a shortcut to accelerate the default configuration saving. It must be noted that an option is available in the Options dialog box (tab Misc) to request that the default configuration file is loaded every time C2A is launched (a default configuration must have been defined before).
It is possible to delete the default configuration file using the commande Clear the default configuration within the File menu.
