Problems with using TrackPopupMenu on win7

Question

I'm trying to create context menu using TrackPopupMenu function in my application, the code I use in it is like the following:

CMenu menu;
        if (menu.LoadMenu(IDR_MENU_TRAY))
        {
            CMenu* pSubMenu = menu.GetSubMenu(0);
            if (pSubMenu != NULL)
            {
                pSubMenu->ModifyMenu(IDM_CLOSE,MF_BYCOMMAND,IDM_CLOSE ,g_cfg->GetLang(TEXT_MAIN_CLOSE,"Exit(&X)")); 
                pSubMenu->ModifyMenu(IDM_SHOW,MF_BYCOMMAND,IDM_SHOW ,g_cfg->GetLang(TEXT_MAIN_OPEN_SHUTTER,"Open(&O)"));
                CPoint point;
                GetCursorPos(&point);                                                                   
                SetForegroundWindow();  
                pSubMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON, point.x, point.y, messageOnlyWnd); 
            }
        }

The code runs perfect on WinXP, while on win7 and vista it doesn't. The Problem on win7 and vista is that it takes a fairly long time to pop up the menu, maybe 1 min or more. But if I turn off the Aero on win7 or vista, it runs smoothly just like on winXP, so I guess somethin must be conflicted with Aero in the code, but I just don't know how to fix it. Is there anyone can help me with that? I will appreciate it a lot if anybody helps me out.

Answer 1

I don't see anything wrong with this code. I've used TrackPopupMenu on Vista without any problems. The source of the problem might lie elsewhere. Try removing the call to SetForegroundWindow. If that doesn't work, try creating an empty project with just the popup menu code.
