Troubleshooting

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

• [X ] Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
• [X ] None of your GUI code was generated by an AI algorithm like GPT
• [X ] If not tkinter - looked for Demo Programs for specific port
• [X ] 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.org
• [X ] Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• [X ] Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

I am wanting to write a menu driven system that opens various windows, each with a menu in them.
I have written a different python file for each window, and I start with a main menu window.
With the main menu window open, I open a second window and it the second window works fine, but I cannot use any of the buttons on the first window until the second window is closed - it seems to buffer the instructions and it only performs them after the second window is closed.
Is there something I can do so that the user can swop between the open windows and use the full functionality of the open windows?

Code To Duplicate

A short program that isolates and demonstrates the problem (Do not paste your massive program, but instead 10-20 lines that clearly show the problem)

This pre-formatted code block is all set for you to paste in your bit of code:

import PySimpleGUI as sg
from try01 import fTry01
from try02 import fTry02
# the main program
def main():
    mInputMain = [
        [sg.Text('This is the main window')],
        [sg.Button('Open 1', key='-OPEN01-')],
        [sg.Button('Open 2', key='-OPEN02-')]
    ]
    window = sg.Window('InputMain', mInputMain, location=(20, 0), resizable=True, finalize=True)

    while True:
        event, values = window.read()

        if event == sg.WIN_CLOSED:
            break

        if event == '-OPEN01-':
            fTry01()
        elif event == '-OPEN02-':
            fTry02()

    window.close()

if __name__ == '__main__':
    main()

# the code that calls a second window
import PySimpleGUI as sg
def fTry02():
    mInput02 = [
        [sg.Text('This is the second window that is being opened')],
        [sg.Text('This will be the second line on the window')],
        [sg.Input('', size=(12,1), enable_events=True, key='-INPUT02-')],
        [sg.Button('Clear02', key='-CLEAR02-')]
    ]
    window02 = sg.Window('Input02', mInput02, location=(400,400), resizable=True, finalize=True)
    while True:
        event, values = window02.read()
        print(f'{event} was clicked')
        if event == sg.WIN_CLOSED:
            break
        elif event == '-CLEAR02-':
            print('clear02')
            window02['-INPUT02-'].update('', background_color = 'red')
    window02.close()

Watcha Makin?

I have written a system in Microsoft Excel (VBA) that plots the drift of an object in the sea so that we can search and find a casualty more easily. I am wanting to rewrite it so that it is independent of Microsoft, but also so that it can run cross-platform.
This is the reason that, at my ripe old age of over 70, I am learning python and wanted to use your wonderful PySimpleGUI
