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 , 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.

I see the same behavior when using… , so I'm reasonably sure that this really is my middle-click behavior for some reason. – Braden Anderson Aug 26 '10 at 2:11
You might look at this software, not sure if it will do what you – Moab Aug 26 '10 at 2:17
Thanks, Moab. Finally figured it out. – Braden Anderson Aug 26 '10 at 2:19

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.

Wow, after all the struggle, it never occurred to me that another app would be responsible for this. Nice to know that it can be fixed. Cheers! – Giraldi Apr 29 '15 at 2:18
