title: SendMessage to click on Non-Client items
body: <p>I am having trouble getting SendMessage to activate a menu on another program.  When looking through Spy++ when a user clicks on the menu the following occurs:</p>
  
  <pre>
   000A0628 P WM_NCLBUTTONDOWN nHittest:HTMENU xPos:1706 yPos:395 [wParam:00000005 lParam:018B06AA time:27:23:56.156 point:(1706, 395)]

   000A0628 R WM_INITMENUPOPUP lResult:00000000</pre>
  
  <p>Whereas when I attempt the same using SendMessage with WM_NCLBUTTONDOWN the following happens instead:</p>
  
  <pre>
   000A0628 P WM_NCLBUTTONDOWN nHittest:HTMENU xPos:1700 yPos:400 [wParam:00000005 lParam:019006A4 time:27:25:02.156 point:(1700, 400)]

   000A0628 S WM_EXITMENULOOP fIsTrackPopupMenu:False [wParam:00000000 lParam:00000000]

   000A0628 R WM_MENUSELECT lResult:00000000
   000A0628 S WM_EXITMENULOOP fIsTrackPopupMenu:False [wParam:00000000 lParam:00000000]

   000A0628 R WM_SYSCOMMAND lResult:00000000
  </pre>
  
  <p>Does anyone know how to get this to work properly?</p>
  
  <p>Cheers</p>
