middle-click cycles windows in windows 7

Question

I'm trying to get synthetic middle-click working in Firefox on a new HP G62 running Windows 7. (That is, I want to open a link in a new tab when I simultaneously press both touchpad buttons.) Originally, it wasn't working at all: clicking both fired both clicks. If I change my left button to middle-click in the Synaptics settings page or use http://cybernetnews.com/helpful-tip-middle-click-on-a-touchpad-laptop-mouse/ , then when I try to middle-click, Windows cycles my active window to the back.

I can't even find references to similar behavior; it's similar to Alt-Esc, but simply sends the foremost window under the cursor (and any, er, foremore windows not under the cursor) to the back of the stack.

I've tried adding HKEY_LOCAL_MACHINE\Software\Synaptics\SynTP\Defaults\HasBothButtonFeature to my registry.

Sorry if I've asked this poorly; it's my first Stack Exchange question. Thanks to anyone who tries to tackle something so esoteric and vague.

Answer 1

This is a KatMouse feature.

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.

Another feature involves the wheel button. Since the wheel button is not consistently used in Windows, KatMouse can use it for a kind of task switching: with a click of the wheel button you can push a window to the buttom of the stack of windows that is your desktop, making a recovered window the active window.
