Insertion Point/Selection Confusion

G'day David,
looking over your spec.'s I think I'd look closely at the mouse driver. I know, I know - what has the mouse driver to do with keyboard input? Well, they're both part of the "Human Interface" subsystem and Logitech drivers are notorious for oddities.
So, if you can, I'd replace the Logitec driver with a MS one - even if you have to go to a MS mouse - and then test thoroughly. If the problem recurs then you know its not the mouse driver - if it doesn't then its a fairly good bet that it is. Only problem with intermittent faults is you never know for sure whether you've fixed it.
My next thing to consider is definitely the printer driver. MS have the printer driver very closely associated with nearly everything presented in the gui so it is definitely worthy of suspicion...
