I am not aware that I intentionally set it to anything...I am afraid I am not that smart. All of the other files open with 2 clicks. The Excel ones are the only ones that I have to single click. But, let me add that I echo Martin's words...Excel is a very powerful tool in AC and I am glad I finally got my flow sheets loaded. All in preparation for making the "BIG LEAP" ( just waiting on my IT guy to wire another station and check over my back-ups). Bert, you are so helpful. I had no idea I could change the name or color of the "Sheet" tabs. I did and they look "mahvolous".
