I have found that I do need to use a trick to get paddles to work in the menu system, maybe try this:
Let's say you have three games on a list and you want to select the middle game. I find that when the menu begins, the [..] back to previous menu item at the top starts out as being the item currently selected.
If I begin turning the paddle, it seems that I need to turn the paddle a significant portion of one rotation before the selector moves down the list. If I keep turning it until it is highlighting the middle game, the one I want to launch, it won't work when I hit Fire.
What I seem to need to do is actually reverse slightly, go a little backward on the paddle, as if to "center" the selector, and then hitting Fire launches the game.
I am guessing there's some middle potentiometer value that the menu needs to receive before it will register what you are wanting to happen, even though it is selected on screen.
So my trick is scroll down to what you want, then reverse a little without moving back up the list, then hit Fire.
You know that seems to fit the issue I'm having. I thought at first it was the old paddles I was using even though I cleaned them up not working right but when it's happening with new ones from Best with their new pot upgrade and it still did it but not as bad.
So either both paddles are too jittery (doubtful since in games they seem pretty good) or like you said the paddle needs to be aligned just right. I'll give it a try next time I fire up the 2600.
