Other potential causes, such as a misconfiguration of mouse drivers, or accidental changes in mouse settings. On laptops, a misconfigured touchpad setting like Pinch to Zoom can also lead to this issue. In this article, we will discuss different solutions to solve this issue.
1. Testing for stuck CTRL key
A stuck Ctrl key might be causing your mouse to zoom instead of scroll. This happens because holding Ctrl while scrolling triggers zooming. To check if the Ctrl key is stuck, use the On-Screen Keyboard. If it is stuck, try releasing the key or tapping it a few times to fix the issue and return to normal scrolling.
2. Disabling Pinch Zoom
If you’re using the Synaptics driver for your mouse, you might experience this zooming problem because of a feature called Pinch to Zoom. If this feature is already disabled and you still encounter the issue on a laptop, it might happen while scrolling with a mouse. Several users have reported that the unwanted zooming stopped after they went to the Synaptics Properties screen and disabled Pinch to Zoom. If the same issue is still occurring or this method didn’t apply to your particular scenario, move down to the next method below.
3. Disable Zoom on Roll with Intellimouse
If your mouse only zooms while using Excel, the “Zoom on Roll with Intellimouse” feature is likely causing the issue. This setting makes the scroll wheel zoom instead of scroll. Disabling this option will revert the scroll wheel to its default behavior, stopping the unexpected zooming.
