+      s.mode=1;
+      s.hwnd=myWnd;
+      s.data_type=mydatatype;
+      s.build_hMenu=mysubmenu;
+    }
+    TrackPopupMenu();
+    if (ret)
+    {
+      if (unrecognized ret)
+      {
+        if (s.mode == 2)
+        {
+					s.menu_id=ret;
+          if (SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU)==0xffffffff)
+          {
+            // build my data.
+            s.mode=3;
+            s.data=my data;
+            SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU)
+            // free my data
+          }
+        }
+      }
+    }
+    if (s.mode) 
+    {
+      s.mode=4;
+      SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU) // cleanup
+    }
+     
+    ...
+
+     WM_INITMENUPOPUP:
+       if (wParam && (HMENU)wParam == s.build_hMenu && s.mode==1)

+  kinda complex and gross, yes?
