+      NB: there used to be some code here which set the initial size of the

+          that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
+          it. To see why, you should understand that Windows sends WM_SIZE from
+          inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
+          from some base class ctor and so this WM_SIZE is not processed in the
+          real class' OnSize() (because it's not fully constructed yet and the
+          event goes to some base class OnSize() instead). So the WM_SIZE we
+          rely on is the one sent when the parent frame resizes its children
+          but here is the problem: if the child already has just the right
+          size, nothing will happen as both wxWindows and Windows check for
+          this and ignore any attempts to change the window size to the size it
+          already has - so no WM_SIZE would be sent.
