Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [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
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

demo program - Demo_Multiple_Windows_read_all_windows_25_lines.py - causes application error if a windows is closed when its not paused.
I have worked out a fix - pasted below.
I am not sure if thats the best way to do it, but it works as far as I can see

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)

Watcha Makin?

If you care to share something about your project, it would be awesome to hear what you're building.

從 Demo_Multiple_Windows_read_all_windows_25_lines.py 開始，使用 tkinter port 執行提供的雙視窗範例。在視窗未暫停時關閉該視窗，以重現應用程式錯誤，然後將行為與回報的修正進行比較。當關閉視窗不再導致應用程式錯誤，且 demo 的事件迴圈仍能正確結束時，即表示完成。
