loading configuration doesn't work properly

[dmedine]

I just noticed that with this latest release the fields Study Root doesn't behave correctly. When I load a saved config file, it fills in the Study Root field with what I had previously saved in the FileName/Template field.

This is a result of a bug on the save side. After saving the configuration file, 'StudyRoot' is equal to the entry I put in the FileName/Template field.
