Popup Menu Problem is not working properly

See more:

C++

Win32

The Below code is to create an popup menu on system tray Icon

VOID DisplayMenu(HWND hWnd)
{
	HMENU hMenu ;
	POINT pCursor;
	hMenu = LoadMenu(hInst,MAKEINTRESOURCE(IDC_GETSCREEN));
	GetCursorPos(&pCursor);
	TrackPopupMenu(hMenu, TPM_BOTTOMALIGN | TPM_LEFTBUTTON | TPM_NOANIMATION, pCursor.x, pCursor.y, 0, hWnd, NULL);
}

this function is being called on click on the system tray menu

IDC_GETSCREEN is a menu resource ID the lay out is given below:
________ __________
|File | | Help |
-------- ----------
|Exit | |About |
--------- ------------

As you see this is the primary menu that is created with new project of Visual C++.

Now My problem is
1. When when I click on the icon on the system tray it create the menu. but the text File and Help is not visible. Even though I can browse through the menu.
2. When I Click on something else the menu does not disappear.

Can anyone point me out my missing points

Thanks in advance

[Edit]I took care of problem 2
with below function:

VOID DisplayMenu(HWND hWnd)
{
	HMENU hMenu ;
	POINT pCursor;
	hMenu = LoadMenu(hInst,MAKEINTRESOURCE(IDC_GETSCREEN));
	GetCursorPos(&pCursor);
	SetForegroundWindow(hWnd);
	TrackPopupMenu(hMenu, TPM_BOTTOMALIGN | TPM_LEFTBUTTON | TPM_NOANIMATION, pCursor.x, pCursor.y, 0, hWnd, NULL);
	PostMessage(hWnd, WM_NULL, 0, 0);
}
