I've downloaded the respected utility X-Mouse Button Control, which can translate button events into other events. Autohotkey is another such application.
I believe my work PC has some utility, either from the hardware vendor or from the firm itself that they're forgetting they install, that is translating middle-mouse button events into Left Windows Logo Key events.
How could I find a list of such event-intercepting/translating utilities currently running?
Is there a registry entry that would translate middle-mouse-button events into Left Windows Logo Key events?
The specific issue I'm interested in is that I have two input devices: a Lenovo SK-8855 USB keyboard, with the Thinkpad key layout and a TrackPoint "mouse" with three buttons, and a Logitech T400 cordless mouse.
With just the default drivers, the Lenovo works perfectly in all respects both as a keyboard and as a three-button mouse. Specifically, the middle-button causes a middle-button event to be generated and fed to the application with focus--good thing for me as a Unix programmer as the Unix apps I'm using via Windows all use this middle button all the time.
Again with just the default drivers, the Logitech also works perfectly in all respects: the cursor moves smoothly. Left and right buttons work. Scroll wheel is fine. And in fact the middle-button is invariably recognized by the OS... but treated as if it is a depress of the left Windows Logo Key. In other words a click of the middle mouse opens the Start Menu. Pressing and holding down middle-button then the X key gives me the "quick link menu" just as chording the Left Windows Logo Key with X.
My aim in asking this question is so that I can determine whether 1) something is simply translating this event--knowledge of which would hopefully let me turn it off--or 2) whether the OS is definitely seeing middle-button events and somehow treating them as if they were Windows logo key events.
