That's not an error message, that is a normal message after a successful compilation.
Can you please tell me how you created an new tab, because I can't find the button indicated in the tutorial to make a new tab.
(but then I still wonder why the tutorial doesn't show it like that).
And indeed, the .ccp file is missing.
But the pitches.h file as shown in the tutorial is not a proper library at all
As I stated, I use IDE version 1.0.4.
I don't know what you mean by "dialog",
but just above the window in which you type the statements of the program there are 5 buttons on the left side and 1 at the utmost right side.
