Treasure of Nadia: (Workarounds)
Short answer
Suggested fix (unconfirmed): Use the arrow keys on your keyboard to change the numbers and position, then press Enter to submit the code. Alternatively, use a controller to bring up an on-screen keyboard.
The problem
I'm at the part where I need to enter the basement of the mansion to speak to Clare. I need to enter the security code to turn off the lasers. The box with the numbers appears but the box with the up and down arrows is not showing so there is no way to enter the code.
What players suggest
If you run into an instance where you have to enter a combination and the on screen controls are missing you can use the arrow keys to set the combination. Up and Down will change the number, le and right will change the number you are working on and Enter to submit the code. Reloading a saved game may also work.
