[power-pro] Dialog 1.07 problem

[Sheri]

Have a cancel item that hides my dialog; all works well if I use the
ESC key or click my quit button to trigger it. But if I use Alt+F4,
the button images, dialog colors and all responses are missing when
the dialog is redisplayed. Adding zero as target for the hide/shows
makes no difference. Scripttrace shows that the same lines are being
executed for ESC vs Alt+F4, but in one case the buttons are still
functional while in the other they are absent (with the exception of
their their borders).
