I'm replaying this for the first time in many years and am stuck in darkmoore castle. The cube in the room full of liches and eyes doesn't change color when I read the plaque and click the switch at the end of the hall. When I looked up a walkthrough on gamefaqs there was a second one on the map, so I'm hoping the issue is just my oldtimers and not a broken game. If the first cube isn't supposed to change can somebody help me figure out how to get to the second one? I think I've been everywhere it's possible to get to without it changing and teleporting me elsewhere. The cube does still teleport me but only to places I can walk to or the room with four teleporters, which don't take me where I need to go

I figured it out. It was the chair to keyboard interface
