Delphi has the habit of crashing on exit from time to time. This time it was quite resourceful in finidng different styles of error-messages:
Quite ordinary
Overlay
Transparent
And finally: Captionless
New messages popped out just after closing the previous one with “OK”. Finally I had to close the delphi32.exe process using the Task Manager. Delphi would be the perfect piece of software if only it’d be more stable.
