Ooh. I'd half expected that the modern Kensington products would have infinite numbers of additional strange buttons; I'm sure I've heard this from someone, perhaps senji. A nice simple one just like my existing trackballs looks ideal :-)

On the subject of Kensington MouseWorks, I don't suppose you as an experienced user know how to get it to keep its settings across reboots on Win2K?

I must have done once, since I use it on Win2K and it seems to. But it's been years since I reconfigured it, so I couldn't tell you off the top of my head, I'm afraid. Remind me when I'm at home (somehow - ring me pre-Calling tomorrow or something?) and I'll poke around a bit.
