Logitech (!) has an iTouch Wireless Optical Mouse with a dedicated "double clicker" on the left side (thumb side, for us righties)... and it's just labeled "Double Click".
It also supports the redefined scroll-button as a double click, but I've hated that for several years on all mice, because it never seems to work reliably.
Allen: I didn't know that! Do you not have to configure anything for it to work?
Actually my point was that regular mice (like the stadard 3-button from microsoft should support an 'actiavte' button by default(maybe at the scroller click?). An iTouch is usually for power users only I would think
Straight out of the box (after losing my temper over the execrable polyvinyl plastic wrap!). It is specifically labeled "Double Click", and doesn't appear to have any configurability at all.
Power user? I'm a programmer by profession, but not really a hardware-oriented kind of guy (makes me nervous to crack the case of my machine). I just wanted a wireless keyboard and mouse, and (IIRC) the Microsoft version was $10 or $20 more.
I agree on the "out of the box" configuration for std mice with a scroller. I've forgotten what the default is now, setting it to double click is second nature for new devices, I never look at the original setting.
BTW, as an aside, I like your blog, and I'm ambivalent about PDC pricing. I'm in the US, and my company/division usually pays for 2 or 3 of us to attend PDC, and at least one VSLive a year, which of course (?) includes travel and lodging. This is not my year for PDC (Oct. 2001 in LA was, and coming after 9/11, that was a TRIP!).
