Seems like the old circular menu class is now incompatible with the new Arduino 1.0 GUI version.
Rober Wagner from the arduino forum described the incompatibility. He also sent to us an email and we thank him for the contribution.
The circular menu seems to interest a lot of people so we decided to "port" the circular menu class into the new Arduino 1.0 GUI.
We will try to describe the class in the future.
Now before starting have a look at the documentation of the "old circular menu".
As always you have to construct the three button configuration on your breadboard.
The down button is on digital port 7 the right button on digital port 6 and the enter button at digital port 5.
In order to find out how to connect buttons on your arduino please read the "arduino and memory how to" tutorial.
