+Note that wxWindows maintains the stack of windows having captured the mouse
+and when the mouse is released the capture returns to the window which had had
+captured it previously and it is only really released if there were no previous
+window. In particular, this means that you must release the mouse as many times

-
-This is an event handler function called when the user has tried to close a a frame
-or dialog box using the window manager (X) or system menu (Windows). It is
-called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
-that the application can also invoke the handler programmatically.
-
-Use the EVT\_CLOSE event table macro to handle close events.
-
-You should check whether the application is forcing the deletion of the window
-using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
-destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
-If not, it is up to you whether you respond by destroying the window.
-
-(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
-the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
-it is not possible to skip window deletion.)
-
-If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to

-The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
