Many thanks for the suggestions guys.  This problem has stumped me for 
nearly a fortnight so I do appreciate your help!

Actually I did try that earlier today.  FWIW it doesn't make a 
difference if I explicitly provide a d'tor  :-(

Thanks Kjell.  You're right, it's exactly the same issue.  I've been so 
wrapped up in it I didn't notice the similarity!  It's getting late here 
(UK time) but first thing tomorrow I'll resume my trouble-shooting on 
that previous issue and report back what I find.

My program definitely doesn't call 'on_hide()'.  However, that bug 
report looks interesting.  Again, I'll take a closer look tomorrow after 
a good night's sleep!  I notice that Murray asked if your patch should 
also get applied to 2.4 and you were a bit skeptical - but to be honest 
Kjell, my experiences seem uncannily similar to that report.  Would you 
mind giving it a bit more thought and decide if the same patch is needed 
in 2.4?  Thanks again for being so patient and helpful.!
