My mouse started behaving erratically. When i write on my virtual keyboard, it has starting adding extrra letters (as you could see when i wrote extra). It double clicks my letters very frequently, which seems really strange. If i write a sentence iit does like you seee here. Weird? Windows 10 logitech moouse. Thaaanks for any inputs! ---

I assumed you had, but it’s a sensor problem. Murphys Law. You aren’t going to trust it and even if you “fixed” it will let you down at an inconvenient time. Invest the $5 ---

Ive bought so many mice - going back to my Atari ST in the 80s. Its a soort of new experience for me. ---

Back in the days of mechanical mice with rubber trackballs, gunk would accumulate inside them. Which gunk could be easily cleaned out. Modern (IOW post- ~2005) mice have no such parts. If you’re getting inadvertent double-clicking or click-pause-clicking that’s in the button switches. Which aren’t disassemble-able nor cleanable. Buy a new one. ---

My mouse started bouncing - I’d scroll down and it bounces the page upward at the end, or worse. Solution I fould online was to blow into the innards - compressed air can is best, although I fixed mine this time just blowing. Dust collection messes up the photosensors. (Sort of like how gunk messed up the mouse ball rollers years ago). Blow into every orfice to dislodge as much dust as you can. If that doesn’t fix it - time for a new mouse. ---

> [@LSLGuy](#): > > Back in the days of mechanical mice with rubber trackballs, gunk would accumulate inside them. Which gunk could be easily cleaned out. The scroll wheel can still accumulate gunk, especially if there are, say, cats around. Took my old Logitech M510 apart after the wheel started acting up and it was completely clogged with cat hair and dust and other gunk which had started filling into the main body cavity. Taking them apart (and re-assembling) can be an annoying chore, though. You’re not really meant to take it part. ---

> [@Loggins](#): > > It double clicks my letters very frequently Spurious extra mouse clicks (switchbounce) is a failure mode of the small mechanical switches that are pressed by pressing the mouse button. It’s an actual failure mode cause by wear, not something that you can clear out with compressed air. The switch is dying. Either replace the switch (which is mouse surgery involving, at least, disassembly, removal of the affected circuit board, desoldering and removing the old switch, inserting and soldering the new switch, and reassembly) or replace the mouse. ---

Taking them apart (and re-assembling) can be an annoying chore, though. You’re not really meant to take it part. I just took my M510 apart too and WHEW was there a lot of hair in there. Dog hair. I had the same issue as you, the wheel was acting up and scrolling was a chore. Sadly, when I put it back together, while the wheel was working like a champ the right click had gotten slightly buggered and it didn’t get better after taking it apart one more time. So I did end up getting a replacement. The old one didn’t go in the trash, it’s just waiting in the bullpen in case I ever need a backup. ---

Fixed this problem on mine by taking it apart and clearing out all the hair and lint around the microswitches under the click buttons. ---

I think you should keep it and just rolllll with it. Adds a cute litttttle stutter to your posts! ---

Seriously, it’s been a decade or more since I last had a scroll-wheel mouse. These are my fave: **[Surface Arc Mouse - Microsoft Store](https://www.microsoft.com/en-US/d/surface-arc-mouse/8mrmszc6vxkc)**. They’re real Bluetooth so there’s no stupid mouse-specific dongle tyng up a USB port like Logitech still loves 25 years after it became an obsolete excresence. The scroll wheel function is just touch sensitivity in the middle between the buttons. So works as well but no moving parts at all; nor any opening to admit gunk. I just wish these mice didn’t have mechanical switches under the buttons. Then they’d last forever. But I have yet to have one fail. I lose them first, typically after about 5 years hard use. ---

That’s cool, but $130 is well outside of my mouse budget. ---

Looks like Microsoft’s answer to the Apple Magic Mouse 2. From what I hear the MS is the superior device in almost every respect. ---

I’ve actually gone plug-in trackball myself for most non-gaming computer activities. Still have to pull the ball out and de-dust every few months, but I like it. [Next page](https://boards.straightdope.com/t/mouse-problem-adding-extra-letters-quickly/1013468.md?page=2)
