Is there any way to have mouse-wheel events sent to whatever window is underneath the mouse pointer, even if it's not the active window? I'd like to have x-scrollwheel capabilities without having to turn on x-mouse.

I'm not sure if this is supported in Windows natively, but a program called KatMouse should do just this:
The prime purpose of the KatMouse utility is to enhance the functionality of mice with a scroll wheel, offering 'universal' scrolling: moving the mouse wheel will scroll the window directly beneath the mouse cursor (not the one with the keyboard focus, which is default on Windows OSes). This is a major increase in the usefullness of the mouse wheel.

I'm already using KatMouse, but it doesn't always seem to do the trick. Oct 14, 2009 at 3:24

N/M, I'm an idiot who needs to RTFD. Still, it doesn't work for some apps, like Document Explorer. Oct 14, 2009 at 3:30

Autohotkey would make it trivial to send, say, a mouseclick to the down button next to the scrollbar.– PhoshiOct 14, 2009 at 10:29

KatMouse uses proper wheelmouse semantics for windows, and can be configured to do scroll mouseclicks for windows which don't support wheelmouse messages, per-application and per-window. It's a cinch to set up that way, too. KatMouse wins for this purpose. Oct 14, 2009 at 15:59
Autohotkey!
CoordMode, Mouse, Screen
SetWinDelay, -1
SetBatchLines,-1
SetKeyDelay, -1
; acceleration
_WHEELACC=0x280000
; max speed
_WHEELMAXN=0x1800000
; automatically activate window
_WHEELAUTOFOCUS=1
return
EasyWheel(d)
; if _WHEELAUTOFOCUS if set, check which window is under the mouse and gives it focus if it hasn't already
; then send scroll event to the control under the mouse
; original code from Shimanov: http://www.autohotkey.com/forum/viewtopic.php?t=6772#54821
{
Global _WHEELACC
, _WHEELMAXN
, _WHEELAUTOFOCUS
Static t, s
if ( A_TickCount > 500+t) {
t := A_TickCount
s :=0x780000
}
else if (s < _WHEELMAXN)
s += _WHEELACC
MouseGetPos x, y, hwnd
h := DllCall("WindowFromPoint", "int", x, "int", y)
if _WHEELAUTOFOCUS && (hwnd<>WinExist("A"))
WinActivate, ahk_id %hwnd%
SendMessage, 0x20A, d*s,(y<<16)|x,, ahk_id %h%
}
WheelUp:: EasyWheel(1)
WheelDown:: EasyWheel(-1)

AHK can do anything :3
