It turns out in my case that my mouse had gone bad, oddly, exactly when I upgraded to Mountain Lion—just funny coincidence.

So after trying everything, except smashing the mouse... I found an old mouse and swapped. It seems to work fine. I think the problem was the mouse.
And, by the way, the old mouse was labled "mouse", and the old replacement is labled "pro mouse"... the only difference is the Pro Mouse has black guts. And works.

This helped me. I thought setting the Double-click to low was to slow down the double-click speed. thx

NVRAM/PRAM in Mountain Lion DOESN'T hold mouse settings any longer...
And I have the same issue of single-clicks that THE SYSTEM thinks are double-clicks with any USB mouse I've tried.
It seems that it started after the last Combo Update or Security Update... I did them together...

Same issue here as Sergio Tezza. Dialog boxes in applications will pop on screen and instantly pop off, files will save as if I've clicked "OK", a file will open with a single click rather than a double click. Just did the Security Update on Monday and all these issues started happening. Anyone else? Any fix???

I found this helpful and it solved my problem:

That doesn't help since I'm using a magic mouse, or mighty mouse or whatever it's called. I've tried all the settings in the mouse preference panel, I've tried reconnecting to the mouse. We have 2 computers here doing the same thing with the same mice -- one is only about 2 months old so I don't think it can be a worn out mouse. Any other ideas??? We are having SO many problems!!!

If you use Magic Mouse, try this: https://www.macupdate.com/app/mac/33095/magicprefs
It speeds it up at least double and sets it a bit more reliably...
