Many, many "start up" issues resolved by CIT. Here are any remaining ones to work through. 

Printing

Can't install a printer for which the driver is installed.

As it is now, dual-sided printer reverts to single-sided printer. That is, one ends up not even having the option to choose double-sided. Even though it can initially be made to see it's double-sided. Or something like that!

USB flash drive

Can't see USB storage device at all. Simple USB flash, 64MB from Dell.

iPhone plugged in by USB (to charge it) is recognized by the computer.

Doesn't retain "don't ask me again" or "remember this" settings

• iPhone: Trust this computer? I say Yes, and remember that. It won't remember it.
