| 2819 | event goes to some base class OnSize() instead). So the WM_SIZE we |
| 2820 | rely on is the one sent when the parent frame resizes its children |
| 2821 | but here is the problem: if the child already has just the right |
| 2822 | size, nothing will happen as both wxWindows and Windows check for |
| 2823 | this and ignore any attempts to change the window size to the size it |
