OK everyone,
I built this counter which is supposed to count continuously up to 10 and down to 0. When I turned it on, I realized that it actually goes 1 step further than the limits I put into; 11 and -1. After spending some time to figure out what might be the possible problem, I decided to start all over again, and behold! this time it began working properly! I, then, compared the two very carefully, and couldn't find even a single difference!! I am totaly confused. I have uploaded the patch that contains two of the counters, and will be glad to have some opinions about that problem...
Thanks...
