Czasami otrzymuję raporty o błędach od klientów, których nie potrafię wyjaśnić. Po Application.Run () w Delphi otrzymuję następujące błędy:

 EOSError: System error: Code:_5 Access denied

W obu przypadkach zrzut ekranu z Eurekalogu jest całkowicie czarny.

Czy ktoś może wyjaśnić, co może spowodować, że GetCursorPos lub GetKeyState zawiodą w ten sposób?
