Vertical Scrolling with mouse wheel - number of lines at a time reverts to 1

2

I would like this setting to stay at 3, but it keeps reverting to 1. In the middle of work, not after a reboot or anything like that. I notice it when web pages / documents scroll vertically slower than I'd like.

I did have to install a driver for this new mouse (MS Wireless Mobile Mouse 3500) which added the tab Mouse and Keyboard Center, but the behavior described existed before that installation.

This happens on the order of .. 5 times a day? Any ideas how to fix permanently?

lenovo e530 running win7.

Me too on a ThinkPad W550s. My trackpad is disabled, scrolling is enabled on my trackpoint but I use that sometimes and don't want to turn it off. Wonder if I can run a script periodically that sets the value in the registry? If there even is a registry key for it. – Samuel – 2016-08-30T13:32:36.540

I've been seeing this issue as well. I have a lenovo T420, also on win7. I move it between docks and use it with synergy. I don't see it as frequently as 5 times a day, usually a few times a week (both with microsoft and lenovo mice in docks, and microsoft mouse over synergy). – MaQleod – 2014-05-12T17:08:58.940

Where'd you get the driver for the mouse? Did Windows find it for you? Did it come from a CD? A website? Is it the most recent version? What driver is it? What happens without the driver? – Raystafarian – 2014-05-12T17:57:47.073

So the laptop I have is a corporate image, I'm unsure about the thinkpad mouse drivers, but the others were installed by windows when plugging in the various mice. – MaQleod – 2014-05-12T18:09:28.250

Does the option in your screenshot literally revert back to "1", or does it remain at "3" while the effect changes anyways? – khaverim – 2014-05-14T08:09:16.323

The number in the screenshot above changes to 1 for me when this problem occurs. Seems less often now, once every couple of days. – Trey Mack – 2014-05-14T15:10:09.980

Your ThinkPad also has a touchpad using a Synaptics driver. That driver interferes with your Microsoft mouse. This is a known issue, and Microsoft's solution is disable scrolling on the touchpad.

That is a pretty old KB (from 2001) and I'm on version 16.1.1.0 of the synaptics driver (the KB references version 5.0.17). Still, I'll test this, it may still be applicable, but I would hope after a decade and multiple operating systems later, this would have been addressed - but you never know. I should note that I'm also not using an intellipoint mouse - intellipoint was discontinued back in 2011. – MaQleod – 2014-05-12T18:12:24.113

Current mouse driver from when it happened today was mouclass.sys and mouhid.sys, file version 6.1.7600.16385 (HID-compliant mouse). – MaQleod – 2014-05-12T18:19:03.753

1@MaQleod I'm willing to bet Synaptics considers this a feature and not a bug. – Jason – 2014-05-12T18:21:01.327

I've been testing for 2 days now, looks like disabling 1 finger scrolling for my trackpad was the answer. (2 finger scrolling is still enabled) Thanks! – Trey Mack – 2014-05-30T19:35:03.660
