why skipping?

[SteveCRM]

cout<<"Enter A Menu Option: ";
	cin>>menuOpt;
	while(menuOpt>4 || menuOpt<1)
	{
		cout<<"Please Enter A Valid Input (1-4): ";
		cin>>menuOpt;
	}

	switch(menuOpt)  //Main game switch statement
	{
	case 1:
			cout<<"1 chosen"<<endl;
		break;
	case 2:
			cout<<"2 chosen"<<endl;
		break;
	case 3:
		cout<<"3 Chosen"<<endl;
		ShowAbout();
		break;
	case 4:
		cout<<"GoodBye!"<<endl;
		return 0;
		break;
	}

why does it skip over case 1 - 3? only case 4 works....why?
