I have the same maddening problem with my Apple mouse. It thinks a single click is a double click, which makes it hard to even select a file in Finder without the file opening, or to check a box (the instant double click unclicks the box). I can barely use the computer - I spend more time waiting for programs to open and closing windows that I don't want open. Menus pop open but instantly close.
I've been using Macs for 25 years, and this level of productivity brings me back to the days of my 8mHz Macintosh Plus - only this is more frustrating.
I have my system pref setting all the way to slow. It makes no difference whatsoever.
I'm using OS 10.6.8 (I have no idea if that is Mountain Lion, Sea Lion, Goat Lion, Snow Tiger, or what). Why does Apple refer to the OS as an animal, but then label the OS in the computer (ie "About This Mac") by number. Why do I have to look up what number Mountain Lion - or cross reference what animal my OS number is? << Sorry wrong thread.
I'm using an Apple mouse that says it is "Mouse". It has a clear top, white guts, no ball or button, perhaps it has invisible button areas, but I have no idea how to adjust or determine what they do or where they are. I suppose I should know what model the mouse is, but why should I have to surf the web to find out? Is it a mouse, mighty mouse, apple mouse, ultra mouse, magic mouse, mouse mouse? APPLE! Please give future mice (mouses?) a unique name or number - and print it on the hardware. My mouse and keyboard are wired. I'm getting wired too trying to fix this.

Just typing this message is a pain. The mouse selects words when all I want to do is place the cursor.
