I'm going through the tutorial for version 0.9, and I'm getting stuck at the section where you are told how to use the PC. I have it turned on and I inserted a floppy disc, but the PC monitor is stuck on the upgrades tab and there are no tabs visible in the top of the screen. I've tried relaunching the game and starting the tutorial over 3 times, but the result is always the same. Other than this, everything else related to the PC can be interacted with properly.
