Menus opening up when dragging scroll bars on Mac after macOS Sequoia upgrade

I just recently upgraded my OS to Sequoia. Things have been going fine for weeks, and then yesterday for whatever reason, I am noticing this strange phenom going on whenever I grab a scroll bar to move it, online in a browser or even in software programs. While dragging the scroll bar, things are popping up on my screen out of nowhere. What do I mean? Well, like, little menus and widgets, like this. You can see the scroll bar in the background, and I was just dragging it downward, and this submenu popped up...sometimes it can be a widget, like the weather, or time and date. I don't know what's going on. I didn't turn anything on or off recently. Any ideas? How do I make this stop?

The only thing I can think of is the mouse is failing. In other words, when you press down to select the scroll bar it doesn't always release when lifting your finger. I actually have that mouse connected to one of my Macs and it still works fine. I can only suggest trying a different mouse.

What do you think is causing this?

Could the mouse be sticking? Dirty inside after all these years? Time to replace it?

Or something else? A setting?

Test a different USB mouse.

We have several Logitech M100 mice, that we use with our Intel and Silicon Mac mini's.

What mouse are you using? The only way that should happen is if you have Secondary click set to "Left side". Try restarting.

One other question, does your mouse list it as a M-U0026 on the underside? Just seeing if we actually have the same one.

Sorry, I'm not a mouse diagnostician. It's not a setting. You're talking about a $8 mouse. As I said, I suspect it's failing and needs replaced.

It's a mouse with a wheel, and a right click, but I never touch either of them, unless I need to right click on something. I use the left click exclusively. I'm looking at System Settings > Mouse, and I'm not seeing anything that would relate to this issue, unless there's something I'm missing??? Do tell...

Also, I should mention, when on a web browser, when I click on a scroll bar, then let go of the click, and move away from the scroll bar, instead of letting go of the scroll, as I move the mouse around the screen, it's still locked on the scroll bar and the page is moving all around. It's driving me nuts.

This one:

My Logitech B100 Corded Mouse

I bought it in August of 2020.

The Apple cordless mouse that came with my MacMini (2018) disconnected constantly. I got sick of it, so I decided to go with a corded mouse, which I don't mind at all. It's been a good mouse for years. I've never had any problems with it mechanically.

Like I stated in one of the above posts, when on a web browser, when I click on the scroll bar, then let go of the

click, and move away from the scroll bar, instead of letting go of the scroll, as I move the mouse around the screen, it's still locked on the scroll bar, and the page is moving all around. I can see the scroll bar move when I'm nowhere near it. It's driving me nuts.
