An update for anyone interested in this issue. I remembered I had a 
spare Cooler Master mouse. I took out the Logitech mouse, and plugged in 
CM. The problem went away entirely.

What I suspect is Logitech's Windows driver does a lot of error-handling 
to make it work seamlessly even when the hardware is actually failing. 
If that is true, Logitech wouldn't be the only one doing that - 
practically every manufacturer would be tweaking his Windows driver for 
'superfluous' exception-handling.

The other bit of news is that Cooler Master is a sensational mouse. If 
you have just a little bit extra to spare for your mouse the next time 
around, don't forget to keep CM high on your priority list.
