More help with the 9 circles

Think of the entire diagram with the 9 circles as a road map for the ball to travel by. The ball enters in a puzzle (through a hexagon on the diagram), travels through the puzzle (being represented by a line), leaves the puzzle (at the end of the line), and travels through the tracks inside the center building (the curved or straight lines on the circles) to get to the next puzzle's entrance. This process repeats until the ball stops, in one way or another. If you need them, here are some hints for getting the tracks in the right alignment: Show spoiler

The only X intersection you don't use is the one in the upper-left; the rest you use only once in the path.
You can put the circles in the right order with as few as 7 clicks.
You don't need to turn three of the nine circles.
The middle one needs to be turned 180 degrees from its original position.

Once you have the circles in the right spots, look at the diagram and figure out which puzzle the ball has to start to have all the bridges raised by the time it gets to the last puzzle. All your hard work is about to pay off!
