I'm hoping one of you will know how to fix this. My mouse is all wonky, it randomly decides whether it wants to single or double click when I single click, if I try to drag something to the recycle bin, or to another folder, while dragging the icon, it stops a few times as though it doesn't realize I'm still dragging, or it opens the file as though I've double clicked. This is a real pain while organizing downloads while I'm trying to highlight several items to move them, and it double clicks ALL of them and then I have to wait while it opens 56 SimPE files.
I've tried following Microsofts advice, but that caused major problems with my computer, and I've tried updating the mouse drivers. It is a wireless Logitech mouse. Should I just give up and buy a new damn mouse?

My husband is having a similar problem with his keyboard, not recognizing buttons randomly. Such as running in a video game and then suddenly stopping because the keyboard doesn't realize he's still holding the W button.

Any tips?
I know it's a long shot but I almost wonder if they're somehow related. Computer conspiracy.

If you have an optical mouse and use it with a mouse pad, then maybe that's where the wonkiness comes from. or maybe you need to change the battery if it has one. Not sure about the keyboard, maybe you have dust accumulated inside it. Also, it may be because of pressing too hard on the buttons.

Switch out hardware. You should borrow your husband's mouse and he should borrow your keyboard. If your husband's mouse works on your computer then you know the mouse is the issue. Likewise if your keyboard works on your husband's computer you know the problem is again the keyboard.

how much can a new mouse and keyboard cost?
oh, and if they are wireless, try changing the batteries; when it first ran out of battery i thought it's broken scince it didn't worked...
and, like croco said, try cleaning the keyboard

"how much can a new mouse and keyboard cost?"

Anywhere from $15 to multiple hundreds depending on what you get. I like cheap $15 keyboards from Wal-Mart as I'm forever spilling crap in them and ruining them, and a cheap optical mouse if I'm not using my tablet mouse. Bells and whistles extra, and optional, depending on your needs.

Heyyy I thought it was just me lol

Well my husbands keyboard and mouse cost over $100, so hopefully we don't have to buy him a new one. Mine are what came with the computer. I don't mind replacing mine. I'm crazy about replacing batteries, I do it everytime the mouse acts up and it never helps. The problem comes and goes too, strangely.

It sounds like the button might have become loose and lost some of it's springiness, causing the random double-clicking issues. That happened with one of my old mice (mouses?) once. If you don't mind tinkering a little bit, you could try taking the cover off and put a suitably small, thin piece of plastic or rubber in between the place where the exterior mouse button meets the actual, tiny clickable button inside. That worked for me, and gave me a couple of extra years out of that mouse.

I'm sure I didn't explain it very well but it's no big deal really, just screw the cover off and you should be able to figure it out. If you mess something up you can still throw that mouse out the window.

That seems complicated. I'll look at it. I may just cave in and buy one. And then runover this one with the car.

Replacing batteries, does that mean you have a wireless mouse and keyboard? Could it be interference?

did you ever clean your mouse my mouse did that and i cleaned it not the surface the cracks and creases and look on the back or (bottom) of your mouse there should be a ball thingy i don't know whats it called there should be arrows going in a circle pointing the opposite way use your finger and twist it to open there should be three little rolly thingy use your finger nail to scrap the dust of of them trust me i had the same thing happen to me this is going to work when i say clean it CLEAN IT
ps. it helps to use like a key or pin to scrap the creases

My trackball does that... every logitech trackball I've ever had does that, it lasts about 1 year and then goes crazy and it is so annoying.... not being able to click and drag stuff is a major handicap... and I'm so used to the trackball I can't figure out how to use a regular mouse anymore... with my arm flinging all over the place and whatnot...

But the poster who said you can try unscrewing the thing and rig it with something is right... that's what I had to do to mine, it works good for a while and then I have to open it up again and adjust it again..

Perhaps I'll try opening at cleaning it. I used to do that before. I do have a wireless mouse but I have a wired keyboard.
