GRJ & cjack, What's different is definitely the $64 question? We are trying to figure it out. Quite puzzling. 

I am using 1 meg pots only for the red and yellow timing. I don't have the fixed resistors installed as shown in the drawing. Rod has these on his PCB I believe, but I don't see how that could be a problem either way?

I've tried different values for each 1 Meg pot along with several timing combinations for red and yellow, each one longer, shorter, same, different block trigger times (with the push button) etc. and all seems well here so far. Tried activating the circuit when they yellow was on. I can't seem to duplicate the problem?

The only quirk I have is when first powering up the bread board, without activating the block detector switch, the yellow comes on for a short time and then switches to green (default state) as it should be with no block activation. It then waits patiently for the block activation switch to close. Seems like this has happened in a few of the circuits we have tried for this project. I suspect this would probably not be noticeable when one was first powering up their layout.
