This is a pretty minor, not-gamebreaking bug, but i thought it might be good to look at-- whenever I press the volume down button on my laptop, it opens/closes the character sheet. And whenever I press the mute button, it makes my character move to the right. I'm on a Dell Latitude E6400, running Windows 7 and Dredmor through Steam. I've had this bug since at least the last version, before the DLC.
