radio button and loss of functionality

I wrote winapi application.Which during creation defined :

Code:

CreateGLWindow(hwnd,"OpenGL",800,600,16,fullscreen); CreateWindow(TEXT("button"), TEXT("Choose Shading Mode"), WS_CHILD | WS_VISIBLE | BS_GROUPBOX,10, 610, 300, 120, hwnd, (HMENU) 0,hInstance, NULL); CreateWindow(TEXT("button"), TEXT("Wireframe"), WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 630, 100, 30, hwnd, (HMENU)IDC_M_WIRE , hInstance, NULL); CreateWindow(TEXT("button"), TEXT("Flat"), WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 660, 100, 30, hwnd, (HMENU)IDC_M_FLAT , hInstance, NULL); CreateWindow(TEXT("button"), TEXT("Smooth"), WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 690, 100, 30, hwnd, (HMENU)IDC_M_SMOOTH , hInstance,NULL);

in CreateGLWindow it calls:

Code:

CreateWindow( wc.lpszClassName, TEXT("Graphics"), WS_OVERLAPPEDWINDOW | WS_VISIBLE,10, 10, 800, 800, 0, 0, hInstance, 0);

The procedure is controlled via keyboard and radio buttons defined above

Code:

case WM_KEYDOWN: // Is A Key Being Held Down? { switch LOWORD(wParam) { //====================== //Move forward/backward // to Z axis //====================== //Move forward case VK_DOWN : stateM->incZ(); break; //Move backward case VK_UP: stateM->decZ(); break; } } case WM_COMMAND: { switch(LOWORD(wParam)) { //Set WIRE Model (Edges only) case IDC_M_WIRE: stateM->setWire(); break; //Set FLAT Shading Model case IDC_M_FLAT: stateM->setFlat(); break; //Set SMOOTH Shading Model case IDC_M_SMOOTH: stateM->setSmooth(); break; } }

When the application is controlled via keyboard it works properly,but when I set one of the radio buttons - it performs the functionality it has to perform when radio- button is checked AND when I want to control via keyboard (after it) I can't no more control it like before.
It seems that application doesn't react on keyboard messages.(But during debug I do see that the keyboard messages are accepted)
Only when I minimize and maximize application window back, the keyboard control start to work properly.
Thank you in advance
