Common problems

Some simulated input commands were not sent successfully.

Please think of the library as a high-level wrapper over Win32 SendInput call. Unfortunately, this is a limitation of the API itself, according to this documentation:

• https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-sendinput#remarks
• https://en.wikipedia.org/wiki/User_Interface_Privilege_Isolation

The easiest way to get around this is to run your application as an administrator.
