[Single File Instance] doesn't work well, if I click the same file more than twice , it will open it again.

It seems the failure is due to 1 second "Reuse Window Lock Timeout": https://github.com/zufuliu/notepad4/blob/cb275770ca7b85c17911241cd231fbefa7b71619/src/Notepad4.h#L123-L125

Open same file within 1 second will open multiple Notepad4.
