Popup menu not showing

Hi,

I have a modal dialog with a list control. Right clicking one of the items in the list control, shows a popup menu. Clicking this popup menu, opens another modal dialog with another list control.

My problem is that I can't display a right click popup menu for the list control in the second dialog. 

I tried

void CMyListCtrl::OnContextMenu(CWnd* , CPoint point)
{
if (GetSelectedCount() == 0)
return ;

if (point.x == -1 && point.y == -1)
{
//keystroke invocation
CRect rect;
GetClientRect(rect);
ClientToScreen(rect);

point = rect.TopLeft();
point.Offset(5, 5);
}

CMenu menu;
VERIFY(menu.LoadMenu(IDR_HISTORY_MENU));

CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
CWnd* pWndPopupOwner = this->GetParent();
SetForegroundWindow();

pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, 
point.x, 
point.y,
pWndPopupOwner); 

}

and I also added to the parent dialog ON_WM_INITMENUPOPUP

Also tried just to create a popup menu on the fly

void CHistoryListCtrl::OnContextMenu(CWnd* , CPoint point)
{
if (GetSelectedCount() == 0)
return ;

if (point.x == -1 && point.y == -1)
{
//keystroke invocation
CRect rect;
GetClientRect(rect);
ClientToScreen(rect);

point = rect.TopLeft();
point.Offset(5, 5);
}

CMenu addMenu;
addMenu.CreatePopupMenu();
// add all possible interface items
CString mstr; mstr="Compare";
addMenu.AppendMenu(MF_ENABLED | MF_STRING,ID_HISTORY_COMPARE , (LPCTSTR)mstr);

addMenu.TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON,point.x,point.y,this,NULL);

addMenu.DestroyMenu();
}

It didn't work as well. Tried to add SetForgroundWindow before the call to TrackPopupMenu, but it also failed.

Any idea what to do ?
