Digital Light & Color

In PWP 5.0, the slide show maker crashes for me if I insert a slide, open the window for editing the slide's properties write something in it, delete the slide while the window is still open, and then insert a new slide. PWP does not crash if the editing window is closed before deleting the slide.

I confirm this behaviour. Is there a practical reason for keeping the Edit Slide Properties window open while deleting the slide whose properties are being edited though?
