Windows – Weird mouse problems. Accidental double-clicking, selection, drag-n-drop problems

driversmousetroubleshootingusbwindows 7

My mouse has started to double click or not keep a selection. Middle click works on the 2nd-3rd try, it ruins drag-and-drops and confuses selecting with opening things. It feels like little "refreshes" that cancel ongoing selections/drags/etc. This makes the pointing device entirely unreliable to the point of driving anyone insane. You think you know, but you have no idea. I would rather it not work at all.

I thought it was a hardware issue, but the mouse works fine on other PCs. This is a brand new HP mouse, a replacement for a previous one which died spectacularly (cursor all over the place, random clicks) some months ago.

I've tried:

  • rebooting
  • switching to another mouse
  • messing with double-click speed in Mouse Settings
  • a debouncing application
  • uninstalling drivers
  • using a different USB port

What's weirder is that certain things slow down the return of the issues:

  • unplugging and re-plugging the USB cable
  • switching the mouse buttons around in Mouse settings

I suspected some mouse filter drivers my anti-virus installed, but that turned out not to be the source of the problems after all… I also believe it may not have anything to do with HIDs at all, but with something else entirely that manifests like accidental clicks. Selecting text with the keyboard works fine.

Any ideas?
I wouldn't like to re-install Windows for this.

SOLVED (?): The problem suddenly vanished, everything has been fine for several hours. I believe uninstalling UxStyle made it go away – that's the only change to my system I can recall. Nope.

It's most likely a problem with the switch (most likely Omron brand). I've had this problem on many Logitech mouses (expensives ones). To save money I had to change the Omron switches myself and now it's ok. You can also just try to fix the switches (you have to rebend a small piece of metal inside, it's not easy and won't last long).

Look on Youtube and you'll find tutorials.

Your USB port most likely doesn't have anything to do with your problem.
