Sometimes when I hit the keyboard and hit a specific letter, the screen breiefly flashes. The only way I can show you an example is if I make a video. I'll do that as a last resort. But, for me, when I press the letter d more than once when Adium is in focus, the screen will do the flashing thing. Is this supposed to happen? I don't recall it ever doing that a while back. I'm on Tiger 10.4.11.
