// [First trick]
// To complete resizing panes before displaying MergeView window,
// it needs to send WM_SIZE message with SIZE_MAXIMIZED to MergeView window before calling ActivateFrame().
// [Second trick]
// But it causes side effect that DirView window becomes restored window from maximized window
// and the process could be visible.
// To avoid it, it needs to block the redrawing DirView window.
// I had tried to use LockWindowUpdate for this purpose. However, it had caused flickering desktop icons.
// So instead of using LockWindowUpdate(),
// I wrote My[Lock/Unlock]WindowUpdate() function that uses subclassing window.
