Mouse wheel scroll causes zoom in/out in Google Chrome

Solution 1:

Dont know where from this problem comes. but we can have an alternative solution to that. Depending on the drivers for your mouse, you could set ctrl-scroll as a "shortcut" to actually do nothing - essentially capturing the combination and throwing it away. Some drivers will even let you specify this for only within a certain application, at which point you'd specify chrome.

OR

Another trick would be:

solution using AutoHotKey posted on google groups:

Using Logitech Performance Mouse MX...

Downloaded AutoHotKey software

In the AutoHotkey.ahk file, added these to do nothing for Cntrl+MouseWheelScrolling

^WheelDown::return

^WheelUp::return

Also if this doesn't work, please provide some more information about your hardware please..

UPDATE - The solution

It looks like the zooming issue is related to mouse scrolling freeware. I took a look at a tool I run called "WizMouse." The purpose of these tools is to allow scrolling windows without focusing on them. Settings can be changed in these to fix the problem.

Resolutions:

• KatMouse (per nsx82): Add class: Chrome_WidgetWin_1, and under the settings tick option: "Window has scrolling wheel support?" (try checked first)
• WizMouse (per JoPa Mi): Uncheck "Enable mouse wheel for applications without mouse wheel support"

Solution 2:

I've been annoyed by this for a long time, but when I searched most recently, I found a Chrome Extension that disables this Ctrl-scroll zoom behavior called No MouseWheel Zoom.

It worked fairly well, but didn't do exactly what I wanted (I wanted scrolling to continue as usual, even if I had pressed Ctrl. The extension just stopped scrolling and zooming altogether when Ctrl was pressed). So, I decided to make my own extension, which I just published yesterday. It converts Ctrl-scroll back into normal scrolling, and it's called ZoomToScroll.

Check these two extensions out and see if either one of them does what you want.
