The best way to figure out what's going on with a signal is to put it on an LED and look at it. If your signals are being naughty, they shape right up and start behaving. This makes it hard to diagnose any problems, but at least you can see the signals acting right.
I did this today with some counters I was trying to make count. Instead of right-acting signals, I got a Las Vegas type of effect, which was kind of exciting, but hardly illuminating. This time, the process of getting the signals into some kind of form that was compatible with the LEDs ended up solving the problem.
You can never have too many LEDs.
