After 30++ years with Delphi and other languages, I decided to learn Python and see what is all about. So I used Delphi and some other libraries to learn. (for me Python is awful) And now to the point While using DelphiVCL4Python I found that pyscripter  or GuiPy do some closing problems on some application So I made this https://github.com/pyscripter/pyscripter/issues/1286 and this https://github.com/Embarcadero/DelphiVCL4Python/issues/92   however today I found out that Microsoft Visual Studio 2019  also works on Python and the program I put closed without any problems So I wonder where is the problem?
