2984           specified. This was wrong because wxWidgets programs often assume
2985           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2986           it. To see why, you should understand that Windows sends WM_SIZE from
2987           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2988           from some base class ctor and so this WM_SIZE is not processed in the
2989           real class' OnSize() (because it's not fully constructed yet and the
2990           event goes to some base class OnSize() instead). So the WM_SIZE we
2991           rely on is the one sent when the parent frame resizes its children
2992           but here is the problem: if the child already has just the right
2993           size, nothing will happen as both wxWidgets and Windows check for
2994           this and ignore any attempts to change the window size to the size it
2995           already has - so no WM_SIZE would be sent.
