How can i disable the "mouse scroll wheel click" to view all windows feature in El Capitan Ive got a mac mini running El Capitan, i use a piece of CAD software which requires me to use the "mouse scroll wheel click" to move around the software. 

This works fine on other machines that i have the software installed on which are running Yosemite, but on this machine running El Capitan the "mouse scroll wheel click" shows all windows, the same as pressing F3. 

Is there a way to disable this feature in El Capitan ?  

For reference im using a logitech LS1 Laser mouse which is a simple mouse which works plug and play, its not a fancy gaming mouse, and it driver software is quite limited (see attached screenshot of options). But because of the way the issue is only showing up in El Capitan im thinking its an issue / setting in the OS rather than on the mouse.
I suspect El Capitan is interpreting this action on your Logitech LS1 Laser mouse as a double-tap with two fingers.

Assuming this is the case, you can try this:


Go to Apple > System Preferences
Click on the Mouse preference pane
Select the More Gestures tab
Uncheck the Mission Control box
