I want to solve the actual problem, not make new ones, since ...

Well, if it's supposed to work in 4.5 and beyond, and if it doesn't work on my
4.8, it's a fair bet that the problem is something in my configuration.  If I
don't fix that, 4.11 may not work either, and I'll have the added handicap of
all the additional variables that the update may introduce.  So suggestions
on things to check first are still very welcome.

I'll need to set a whole day aside for the upgrade to deal with surprises.  I
won't get that for at least a week and a half, so I have plenty of time to
check other things first.
