Several dialogs already null their global at the top of DestroyWindow, but a few do not: briefing, debriefing, event, background, message, cutscene, goal, and Fred_view_wnd. OnClose nulls in those five cover the user-initiated close path, but any teardown that bypasses OnClose leaves a dangling pointer that could be dereferenced.
