Thanks !!  using a slight variance of the sequence described consistently
causes my Windows Wireshark to crash.

So far by a process of simplification I seem to have narrowed the problem down
(if I'm not being deceived) to main_widgets_rearrange().

That is: Doing basically just the following during the prefs_main_apply_cb
causes a crash:

   prefs_main_fetch_all();
   prefs_apply_all();
   main_widgets_rearrange();
   cf_redissect_packets():   crashes (eventually)

There is no crash if main_widgets_rearrange is not called.

So: I'm studying what goes on during main_widgets_rearrange() ...
