Suddenly HOVERING is causing automatic actions in various apps

The Pool Man · 26 Oct 2019

I can't think of anything I've changed to my system except for the recent cumulative update. All of a sudden if I hover over certain apps... umm... things happen.

In VLC the volume automatically rises to 200%. If I hover over the video's timeline it begins advancing through the video.

If I'm in Firefox or Chrome and I hover over YouTube's audio levels it automatically lowers the volume without me clicking.

If I'm in system settings (as you might imagine I would be) and I scroll down a page, it scrolls back up by itself.

Is this some sort of Ease of Access feature that got turned on?

Defective mouse? Try a different mouse or your touchpad.

I have a wireless and so I plugged in a wired mouse. Same thing.

Is there an overall mouse driver? Or should each mouse have different drivers?

(Thanks for response.)

Did not replicate issue on updated laptop, so I think this is simply my desktop PC in trouble.

I think a generic mouse driver is normally used if a specific model driver is not found.

Try disabling "Scroll inactive windows when I hover over them" at Settings, Devices, Mouse?

... and another setting to check is in Control Panel:

It wasn't enabled. For spits and giggles I activated it, applied, deactivated it, applied, and rebooted.

Nada.

Which type of driver should I look for -- because both the wired and wireless mice behaved the same way.

New symptom -- for fun it sometimes increases the magnifiation of my Firefox windows a little.

I've SFC'd, DISM'd, Full Scan Defender'd, Malwarebitten, and tried Safe Mode.

Nada pinata.

I'm thinking I may have to roll back to prior version of Windows... but I'd like to avoid that if possible.

Oh you're not going to believe this. Earlier I was asked to check the mouse situation. And so I plugged in a wired mouse and got the same issues. However, that result made me overlook one simple something --

-- unplugging the bluetooth dongle for my wireless mouse. I mean, why bother, right? If the wired one had the same issue.

But I did it anyway. Unplugged, replugged.

FIXED.

sssheeeeeshhh
