So, when I use the little dial, the required buttons aren't clickable (i.e., flame, etc.). The only clickable button is the "Shadow" button. So I'm stuck in the library.
That's a weird bug, do you have a savegame file?
Did you happen to accidentally or intentionally click the "Downgrade 32-bit graphics to 16-bit" option in winsetup.exe?
The game needs to be running at 32-bit so that it can detect the color maps correctly which link up to those dial buttons. But rarely, some graphics cards might take the liberty of auto-downgrading the game's graphics to lower than 32-bit, which would cause this bug to occur.
Could you run the demo and press CTRL+V. In the resulting textbox message, it should say something like "Running at 640x480 at 32-bit". Can you let me know how many bit the last part says?
GameDevChris - That was indeed the problem. In the winsetup file, I had pressed the downgrade to 16-bit option. (My graphics card was having issues with the resolution, so I had played around with the winsetup file to get it to run; turns out all I actually needed to do was turn off the graphics filter, not downgrade to 16-bit.)
The dial works fine now. Thanks!
