I'll bear that in mind in future. :-)

When using the 10X setting on the probe and the scope set on
0.1v/div., the p-p waveform occupies just over 2 divisions. I guess
that equates to 2.2v?

SFAICS, these are both negligible WRT the signal.
What I *cannot* understand is why on the x1 probe, Vin is four times
larger than Vout., whereas with X10., the signal levels are almost the
same. It's a heck of a discrepancy. Can anyone enlighten me?
BTW, your screen shots were very helpful. What simulation program do
