The system("pause") at line 32 may have something to do with that. Happens when you press a key?

With the system pause, when you hit a key the invalid entry just comes up again. Without the system pause, the screen just flashes back and forth between the menu and invalid entry screen without enough time to even read what it says

Try putting:

cin.ignore(1000, '\n');

in the else clause.

[#define]

The variable selection is an int. When you attempt to enter a character the cin stream will fail. Subsequent cin calls will skip due to the stream being in a fail state.

    cin >> selection;

You could use the clear function before the next read.

    cin.clear();
    menu(selection);

Another option would be to use a character type for the selection variable.
