Just for the record -- the latest driver for Wacom-4, 614-3, is no good for two pens, one of which is the classic (and I believe is no good, period but can't prove it). What Asaf has described in his Wacom driver posts more or less supports my own bad experiences and he does not have the classic pen as far as I know. At times I have thought I have everything under control, until some small matter of operating other apps on my computer threw apart the whole tenuous house of cards (using a Logitech mouse, for instance, which Wacom man says "We don't have around here").
Having spent altogether three lengthy conversations with ITs on the Wacom phone line who never came up with any helpful solutions lasting more than a week, I have made the big step backward, returning to driver 611-3, which is the one my Wacom4 came with, and I am once more happy... that one does work for me without a hitch. The one thing I do miss a lot however is the Wacom Preferences utility that comes with the two recent upgrades. Maybe I should donate Wacom a Logitech mouse to work with on the next upgrade.
