Thank you for downloading!
I understand that there are three conditions under which the backlog appears:
・Pressing the 'Backlog' button in the message window
・Scrolling up with the mouse wheel
・Pressing 'Y' on a gamepad
Do you mean that the backlog suddenly appears upon startup without any of these actions being performed?
If possible, could you let me know the environment in which you are playing the game (whether you are using a gamepad and your operating system)?
For troubleshooting purposes, I would also like to know what happens when you start the game after disconnecting each of the keyboard, gamepad, and mouse separately.
