cin is not blocking (C++)

Hi

I'm trying to write a little text based application and this is my code:

   void loop()
    {
        std::string selection;
        
        cout << "Initializing Manual Sampler Thread" << endl;
        while(true)
        {
            cout << "Command:" << endl;
            cin.clear();
            cin >> selection;
            
            cout << "<<selection" << selection << endl;
        }

But it comes out as:

It is supposed to block on cin where it says the command prompt but instead it just

steamrolls right through it.
