I am not a an expert, but this small program I wrote is working perfectly on a Win7/64 computer but shows the same error on a real windows10 and on a VMware VM.
could well be a wrong compiler setting... have no clue, so asking for help. Attached screen shots showing that the application is running correctly, but GUI doesn't pop up, so is not visible on the desktop, but moving the mouse on the taskbar Icon, it shows that the program is there, running, just waiting for someone to click on the TButtons.
Attaching only the relevant part of the desktop, and just 1 of the 2 windows 10 problems, because of attachment size limit.
