Doron: Do you know if there are actually any mice in production yet that send HID reports that would result in a MOUSE_HWHEEL being sent by the HID mapper?

Last time someone asked this question, it was discovered that the mouse didn't send horizontal scroll messages directly, but had a separate Top Level Descriptor that their special service was opening and reading rather than going through the "standard" HID mechanism.

In fact, I'd be kind of surprised if this *ever* takes off, at least until no one cares *at all* any more about OS's where MOUSE_HWHEEL isn't supported (do you have to go back to 2k or only XP to find that? I don't remember).

Unlike some kinds of peripherals vendors *really* don't like to make mice that only work on some machines, so my (completely ignorant, but well educated) guess is that they *all* still use the separate TLD method. And if they have to do that anyway, it's actually a heck of a lot more complicated to also include the "standard" way. So I bet they don't.

Still just a guess, though :-).
