Recently I've run into a small, yet very annoying problem with my computer mouse. For the past two years, I've had some kind of Logitech mouse that's worked like a charm- it has a 6 month battery life (or two, if I forget to shut it off at night), it's comfortable, and the USB can fit into a pocket on the underside for travelling. Last week, however, it began to execute a double click at random after I had clicked once. I could no longer rely on it- it would be as frequent as 1 in 2 clicks.
This is a common problem with mice, particularly Logitech mice, and there are many different "solutions" floating around the web. Thank god I have no background in the mechanical side of technology, or I might have taken the whole thing apart. But that route is unnecessary, as I recently discovered two fixes that seem to work for many people.
1. The "anyone can do" fix (suggested on the Logitech help site):
Unplug the USB, take out the batteries, and blow under the crack of the left mouse button. Click both buttons for 30 seconds to remove static electricity, then give it another blow. Then, try the mouse out. If it doesn't work the first time, try one more time.
If you're still stuck, proceed to #2.
#2. The "need to know what an internet is" fix (suggested on a geek forum):
I happened upon this download yesterday that provided a temporary solution to the problem and, if #1 hadn't worked, would've satisfied me enough to not buy a new mouse. It's a downloadable application that uses some kind of voodoo to block the mouse from double clicking when you don't want it to. I'd say it works about 80% of the time, which was enough for me. As I found a better solution rather quickly, I don't know if this is a one-time download or if you need to start it up every time you power on your computer/mouse.
The application seemed to work for everyone who tried it. For anyone who doesn't believe my voodoo theory, I don't have a background in technology (or anything, really), so that explanation is enough for me to trust it.
EDIT: After a long time working without an issue, my mouse started misbehaving again, which I assume happens to them all. I just got a new, quality mouse from Logitech for $40 which has made my life much easier. My recommendation to everyone is to treat these measures as temporary fixes and ask for a new mouse for your birthday.
There are other ways of fixing this problem. If you're familiar with the mechanics of mice and other computer hardware, you can take the mouse apart and look for switches with dust or other grime caught in them that might be causing it to stick. It also could be a drive issue (which means, DON'T TAKE THE MOUSE APART IF YOU DON'T KNOW WHAT YOU'RE DOING since you could break your mouse for nothing). Fix #2 covers all of the root problems. In the end, I would check the mouse out that I bought, or another mouse. I do not regret spending the money after living with the old one and its problems for several months- it was worth it.
