Reinstalled my old Gametek Feud (or is it Fued) game today. Works fine, except for the computer players. They type an answer, but the game fails to input it...instead, it waits for the clock to run out.

Any idea on what might be causing this problem?

Yeah, you're trying to run a fifteen-year-old piece of software on a modern system that isn't designed to handle it.

In industry parlance, we call this a PEBKAC issue.

You might have better luck running it in DOSBox.
