// StartProgressDialog creates a new thread to host the progress window.
// When the window receives WM_DESTROY message StopProgressDialog() wrongly
// attempts to re-enable the parent in the calling thread (our thread),
// after the progress window is destroyed and the progress thread has died.
// When the progress window dies, the system tries to assign a new foreground window.
// It cannot assign to hwndParent because StartProgressDialog (w/PROGDLG_MODAL) disabled the parent window.
// So the system hands the foreground activation to the next process that wants it in the
// system foreground queue. Thus we lose our right to recapture the foreground window.
// The way to fix this bug is to insert a call to EnableWindow(hWndParent) in the WM_DESTROY
// handler for the progress window in the progress thread.
// To do that, we Subclass the progress dialog
// Since the window and thread created by the progress dialog object live on a few
// milliseconds after calling Stop() and Release(), we must not store anything
// in member variables of this class but must only store everything in the window
// itself: thus we use SetProp()/GetProp() to store the data.
