Do not use last folder at startup

I did just an update and my friend did the same.
Now when we drag and drop a music album from our disk in mp3tag main windows; and close the application; every time we reopen mp3tag is reading that folder again and again.
Why, we do not need that folder anymore. In the older versions when you start mp3tag the main windows was empty. Even clicking on DEL (no tracks in main window anymore), closing and reopening the app is re-reading al the folders. We do not want that behaviour.

How can we fix this please????

On the observed behaviour see e.g. here:

it is okay: in the latest version the setting: start with older map was enabled.
Now we set it CLEAN startup.
