Every now and then I’ll single-click on something and the computer will interpret it as a double-click. This can get to be very frustrating when I’m playing a game, and I’ll start to move somewhere when I only meant to just click there. Or I could be clicking the top left hand icon of a window for some reason, and it’ll just close. Or maybe I’m only meaning to click on an icon to move it, but instead will launch the program. Is there some sort of setting that’s turned on that I’m missing? Or is it just a bizzare quirk with my mouse that I should get used to or replace the mouse?
The only thing I think of is a setting in some Windows tweak utilities (TweakXP, TweakUI etc.) have a setting that “detects accidental single clicks” so, look in your mouse control pannel, or other tweaking software first. After that look for any software (you have running) that serves as “short cut managers” or the like
It sounds like the mouse button is bouncing. That is, there isn’t a perfectly clean transition between the two button positions. Actually, all mouse buttons bounce (because of the elasticity of the components), but there is circuitry to eliminate the bouncing. This circuitry will eliminate the rapid on-off-on-off with a frequency higher than some value. With use, the wear on a mouse button can cause it to bounce at a frequency lower than the circuitry is designed to cope with. When this happens, a single click can be interpreted as more than one click.
The easiest solution is to buy a new mouse. They’re cheap.
