some subtle issue with Windows Server 2019

egsuh:
I compile an application on Windows Server 2019. Sometimes the application start again when I click on controls --- checkbox or button, while running within IDE. Once restarted, it runs fine. Running compiled exe file has no problem.

The recent case this happened was at clicking checkbox. And I looked into object inspector and I set autosize property of the checkboxes to false. Then, the whole IDE shut down.

So which pieces of critical information have you not provided?

Thaddy:
Yes, that needs some code, probably. Can you provide a simple, compilable example that reproduces it?

egsuh:
I tested it again, and it repeats consistently.

- Open the project attached,
- Make some changes to the code (of unit1), and Press F9,
- Do some operation --- What I did were:
1) checking some of the checkboxes
2) changed edit1.text
3) pressed button1, and OK
- Then I close the window by clicking top-right corner x,
- The app window appear again --- runs again.

But here, once I close the second window, then there are no further replication.

And if I close the Lazarus IDE, reopen the project, and no change of code, then no replication.

When I run compiled exe file directly, no replication.
