Thanks, Robert. That's cleared up a few more grey areas for me. The
reason for the delay in replying is that I grasped the nettle,
having read a number of posts where it said that the latest build
was quite stable, and installed 14.0.8050.1202, since when I've had
more crashes than I had in over a year's operation of 12.0.1606
Just a couple of questions - why (I'm more interested in the 'why'
than the 'how') would anyone wish to specify 'Headers only' as a
sync option, since as far as I can see there's no difference at all
between that and 'All messages'? And equally 'Get ... headers' seems
to do exactly the same as 'Sync selected newsgroup'. I notice that
F5 is now officially a shortcut for 'Sync all newsgroups'.
