DirectX Mouseinput

[WhileTrueDo]

hallo ihe lieben :),

ich habe ein kleines problem mit dem mousebutton input. undzwar wird der mousebutton immer nur als gedrückt behandelt, wenn sich die maus bewegt, ich brauche ihn aber auch , wenn sich die maus nicht bewegt. mein code sieht folgendermaßen aus :

LRESULT TestApp::MsgProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
	//LEFT KEY
	LeftMouseButton.WasDown = LeftMouseButton.IsDown;
	LeftMouseButton.IsDown = false;
	LeftMouseButton.IsReleased = false;
	//

	//RIGHT KEY
	RightMouseButton.WasDown = RightMouseButton.IsDown;
	RightMouseButton.IsDown = false;
	RightMouseButton.IsReleased = false;
	//

	MouseMoved = false;

	switch (msg)
	{
	case WM_DESTROY:
		PostQuitMessage(0);
		return 0;

	case WM_MOUSEMOVE:
		GetCursorPos(&curserPos);
		MouseMoved = true;

	case WM_KEYDOWN:
		switch (wParam)
		{
			//F1 KEY
		case VK_F1:
			m_bHandleDeviceLost = !m_bHandleDeviceLost;
			return 0;
			break;

			//F2 KEY
		case VK_F2:
			CameraPos = D3DXVECTOR3(0.0f, 0.0f, -6.0f);
			CameraTarget = D3DXVECTOR3(0.0f, -5.0f, 1.0f);
			break;

			//F11 KEY
		case VK_F11:
			PostQuitMessage(0);
			break;

			//MULTIPLY KEY
		case VK_MULTIPLY:
			m_pDevice3D->SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME);
			break;

			//DIVIDE KEY
		case VK_DIVIDE:
			if (SwitchState(lighted))
				m_pDevice3D->SetRenderState(D3DRS_LIGHTING, false);
			else
				m_pDevice3D->SetRenderState(D3DRS_LIGHTING, true);
			break;

			//ADD KEY
		case VK_ADD:
			CameraPos.y += 0.2f;
			CameraTarget.y += 0.2f;
			break;

			//MINUS KEY
		case VK_SUBTRACT:
			CameraPos.y -= 0.2f;
			CameraTarget.y -= 0.2f;
			break;

			//UP KEY
		case VK_UP:
			CameraPos.z += 0.2f;
			CameraTarget.z += 0.2f;
			break;

			//DOWN KEY
		case VK_DOWN:
			CameraPos.z -= 0.2f;
			CameraTarget.z -= 0.2f;
			break;

			//RIGHT KEY
		case VK_RIGHT:
			CameraPos.x += 0.2f;
			CameraTarget.x += 0.2f;
			break;

			//LEFT KEY
		case VK_LEFT:
			CameraPos.x -= 0.2f;
			CameraTarget.x -= 0.2f;
			break;

			//NUMPAD1 KEY
		case VK_NUMPAD1:
			lantern1->SetGlowingState(false, d3dColors::Green, d3dColors::Green, m_pDevice3D);
			lantern2->SetGlowingState(false, d3dColors::Green, d3dColors::Green, m_pDevice3D);
			lantern3->SetGlowingState(false, d3dColors::Green, d3dColors::Green, m_pDevice3D);
			break;

			//LEFT MOUSE BUTTON
		case VK_LBUTTON:
			LeftMouseButton.IsDown = true;
			break;

			//NUMPAD1 KEY
		case LK_E:
			SwitchState(SystemCls->active);
			break;

		//	//NUMPAD1 KEY
		case VK_NUMPAD8:
			if (SystemCls->active)
				SystemCls->InfoOutSprite->SetPosition((SystemCls->InfoOutSprite->GetPosition(*"x") + 10), (SystemCls->InfoOutSprite->GetPosition(*"y") + 10), (SystemCls->InfoOutSprite->GetPosition(*"z")));
			break;
		}
		if (LeftMouseButton.IsDown != LeftMouseButton.WasDown && LeftMouseButton.WasDown == true)
			LeftMouseButton.IsReleased = true;
		if (RightMouseButton.IsDown != RightMouseButton.WasDown && RightMouseButton.WasDown == true)
			RightMouseButton.IsReleased = true;
		return 0;
	}
	LeftMouseButton.IsDown = false;
	if (LeftMouseButton.IsDown != LeftMouseButton.WasDown && LeftMouseButton.WasDown == true)
		LeftMouseButton.IsReleased = true;
	if (RightMouseButton.IsDown != RightMouseButton.WasDown && RightMouseButton.WasDown == true)
		RightMouseButton.IsReleased = true;
	return DefWindowProc(hwnd, msg, wParam, lParam);
};

vllt könnt ihr mir ja weiterhelfen.
schonmal vielen dank für eure hilfe,
