Weird Mouse Problem

I'm using a Logitech MX500 Optical Mouse running Windows XP.

My mouse has started to act strange, as it randomly will double click when I single click at times annoying the shit out of me. I'm not really sure why or how to go about fixing it at all, I've only had the thing for two years now.

I've tried to update my mouse drivers, that failed. I checked every possible setting to see if there were any issues, and there weren't. Again, I'm not really sure how to go about this problem because I don't really know where the issue is. Any help would definitely be appreciated.

Jam it back in, in the dark.

Any other computer you could try it on? That would seperate it out from either something physically queer with the mouse, or a software/driver issue.

How ya doing, buddy?

I didn't think it would be the mouse itself, but I guess it is. I plugged it into my sister's computer and it started doing the very same thing there.

It's not really worth trying to open it up and fix it manually is it?

This thing is sticky, and I don't like it. I don't appreciate it.

No, it isn't. Get yourself a new one for Christmas!

I am a dolphin, do you want me on your body?

It's only two years old. In Europe most Logitech products have had a five-year warranty for a long time now; just get it replaced. I think even the latest MX Revolution has something like a three-year warranty, though i'm not sure. I had to get my MX1000 replaced last year; they sent me out a completely new unit in just a few days without even waiting for me to return the old one.

In certain types of mechanical switch a fault develops where if clicked, the switch components rebound a few times (more than they should normally) because some of the parts have become worn. This is an undesirable effect called "bouncing" in electronic terms, and so designers develop circuits specifically to only accept one switch closing operation within a certain time period. This is called a "debounce" circuit.

I have seen this problem in a lot of electronic devices, leading me to believe that most manufacturers rely on the quality of the switch to open and close cleanly rather than on any debounce circuits. With a mouse there is also the chance that the user may simply be clicking the buttons very quickly (eg during a game) in which case a debounce circuit might be more of a hindrance.

I was speaking idiomatically.

I would actually send it in to get it replaced, but it was part of the whole Dell package when I ordered a new computer from them back then. A big mistake, I know. It's the last time I'm ordering from a company, gonna build my own lol.

But anyway, I have no idea at all how to approach the situation under that set of circumstances. Would Logitech even honor a warranty on their product if the product came from Dell as part of a package?

What kind of toxic man-thing is happening now?
