I have been working on this project for almost a week, and have been moving single points just fine using the direct select tool. At first, I was struggling with how to select and move a single point. I found if I clicked it 3 times, moving on the third click, it would move just fine for me.
Now even that isn't working.
I assume I changed an option or something, but do not know what it was.
Final Answer:
Just using the 'A' allowed me to isolate the single anchor point to be moved.
Thank You Lucian

merely activates the Direct Selection Tool. You shouldn't need "3 clicks" with it either. Just one. Sounds like maybe you were using the wrong tool.
