Example in docs not working

The bottom-most example doesn't work for me:

Code: Select all

; This GUI allows you to register primitive three-key combination hotkeys:
Gui Add, Text, xm, Prefix key:
Gui Add, Edit, yp x100 w100 vPrefix, Space
Gui Add, Text, xm, Suffix hotkey:
Gui Add, Edit, yp x100 w100  vSuffix, f & j
Gui Add, Button, Default, Register
Gui Show
return

ButtonRegister() {
    global
    Gui Submit, NoHide
    local fn
    fn := Func("HotkeyShouldFire").Bind(Prefix)
    Hotkey If, % fn
    Hotkey % Suffix, FireHotkey
}

HotkeyShouldFire(prefix, thisHotkey) {
    return GetKeyState(prefix)
}

FireHotkey() {
    MsgBox %A_ThisHotkey%
}

GuiClose:
GuiEscape:
ExitApp

FireHotkey() is called regardless of the HotkeyShouldFire() return value, meaning that only the suffix hotkey field matters in the example. I wasn't able to make the Hotkey If command work together with a function.

Oh, it seems I installed an old version.
