SOLVED: how to remove middl-click hotkey from Explorer?

[Curt]

I don't know but I don't think Middle-click (in white area in Explorer) => "Go to parent folder" is a native Explorer shortcut hotkey in Win 7 - but my Explorer has it. I don't like it; Double-left-click is already giving the exact same effect. I #feel# certain Microsoft did not give me two almost identical accelerator keys for the same feature, so I #guess# the hotkey must have come from some program I have been trialing but now have removed; I have searched all installed programs to look for hotkey settings.

So my question is, how can I now remove this unwanted feature? I wanted to test Folder Menu 3 that uses Middle-click in Explorer (and on the desktop) to open its menu, but it would only seldom do so, most of the time Explorer would jump to the mother-folder instead. I was of course hoping FM3 would override Explorer, but that only happened a few times.

On the Internet I have found several articles on how to change keyboard shortcuts, but I have not found any relevant article regarding the mouse's wheel. So I need to ask you guys:
How to remove middle-click hotkey from Explorer?

64-bit Windows 7 Home Premium DESKTOP. Simple mouse, left-middle-right; no extra buttons.

The mouse middle-click feature did not come from Windows:

The following app will detect what global keyboard shortcuts (hotkeys) are currently registered on the computer by various applications:

After using the software, I noticed that the mouse buttons are not listed...sorry

-thanks,  NewKreation.  
I knew about the program but not about the site; now a useful shortcut  

A problem with this middle-click is of course that it is not a global feature, but for Explorer only; Ethervane ActiveHotkeys and other similar scanners cannot find it.
Besides:

This application does not work correctly on 64-bit versions of Windows. Use it on 32-bit versions only.

If you can't figure out where this assignment came from, you could always re-assign ("over"assign?) the middle click action to nothing when triggered in an explorer window.  Should be easily done in AutoHotkey.  Treating the symptom and not the cause, but how desperate are you?

[Curt]

I no longer care for the diagnose, only the cure.

I have both AutoHotkey and AutoIt installed. What to do next?

something like:

#IfWinActive, ahk_class ExploreWClass
MButton::
return

[Curt]

wow, that was easy!
Thanks a lot, AndyM
