Need clue on the page 680???
On the page 680, step 4 - Add a reference to the PongEngine project inside the solution,
is this step same as on the page 386-387, first, to click the PongEngine.vbproj file to the PongServer and select Add Reference and click the Projects, and you will see PongEngine.
My question here is, I did same steps as on the 386-387, but it looked different and I could not see the PongEngine on the Projects of the Add Reference.
