Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• [ x] Searched main docs for your problem PySimpleGUI Documenation
• [ x] Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demo Programs
• [x ] None of your GUI code was generated by an AI algorithm like GPT
• [N/A ] If not tkinter - looked for Demo Programs for specific port
• [N/A ] For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• [ x] Run your program outside of your debugger (from a command line)
• [x ] Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.com
• [x ] Upgraded to the latest release of PySimpleGUI on PyPI (Version 6)

Detailed Description

I noticed that _last_location is initialized as (None,None), but then is never updated/initialized if you run a pysimplegui program and quit it without ever moving the window. My quick fix is to do:

        def _auto_save_location(self):
        """
        Internal function to save the location of the window in the settings file
        :return:
        """     
        if self.auto_save_location:
            # If the window is not moved, then (Null,Null) is the
            # location, so don't try to save it.
            if None not in self._last_location:
                user_settings_set_entry('-LAST WINDOW LOCATION-'+self.Title, self._last_location)

Then, if the window isn't moved, quitting and restarting places the window at its prior location, or the default location if a location wasn't moved at all initially. Not sure this is the best/proper fix, but it works for me for now.
