UI - Mouse wheel middle click zooms and pans

I'm having some trouble with panning the UI. The issue is that whenever I click the middle button to pan, it also zooms in. If I hold the middle button down steady, it will continue to zoom in. This makes navigating through a schematic a huge pain. The only way I found to get around this is to change the mouse wheel zoom to 1 or 0, however both of these options eliminate zooming by scrolling the mouse wheel. I have the default 6.2.0 install for Windows.

Is there a way I can fix this so that I can pan with the middle button without the annoying zoom in and still be able to zoom by scrolling the mouse wheel?

Hi,

I was having the same issue here, but I use OpenSuSE linux, 12.3. Maybe this can be usefull for windows users too, although I have no experience with windows settings.

After some research I found out what the problem was. My X11 mouse configuration was incorrect. There is an "Emulate3Buttons" setting that was "on". This is certainly wrong in my case, since my mouse has the middle button on the wheel. This means that to produce the middle button I had to press simultaneously the left and the right mouse buttons. And indded, when I did that, I was able to pan.

At the same time, there was another wrong setting, which was "EmulateWheel" "on" together with "EmulateWheelButton" "2". That is what was causing the middle mouse button to zoom instead of panning.

In my case, these settings could be found in the file /etc/X11/xorg.conf.d/11-mouse.conf. To find out the exact entry that is beeing used, you must search for the mouse driver recognized by X11 in the file /var/log/Xorg.0.log. These were the changes I did on 11-mouse.conf:

Section "InputClass"

        # Novell Bug #671776

        Identifier      "ImPS/2 Generic Wheel Mouse"

        MatchProduct    "ImPS/2 Generic Wheel Mouse"

        MatchIsPointer "on"

        Driver "evdev"

#        Option "EmulateWheel" "on"

#        Option "EmulateWheelButton"    "2"

        Option "EmulateWheel" "off"

        Option "EmulateWheelButton"    "2"

        Option "YAxisMapping"    "4 5"

        Option "XAxisMapping"    "6 7"

#        Option "Emulate3Buttons"    "on"

        Option "Emulate3Buttons"    "off"

        Option "EmulateWheelTimeout"    "200"

EndSection

This is what I get on the log (now fixed):
