Constant and intempestive double clicking

Hi X423424X (well this is a strange name),

No, my mice do not have their own software I installed, I simply plug them in and it works.

Yes, the problem happens using another account.

I have been trying the different solutions I found in this thread (https://discussions.apple.com/thread/856573?start=0&tstart=0).

I'm to try the SMC reset and Safe Mode.

Hey I'm back from the SMC reset.

Right now, the problem seems to be knocked out. However, I'm waiting a little bit since during the past days the problem sometimes seemed to be gone (or was I very very lucky?) but went back.

I will let you know in the following hours if the solution is indeed persistent.

Neurotically yours,

Uzume.

As I feared, the mouse is still crazy.

Hi again X423424X, the same thing occurs when I am in safe mode.

Hi John,

Actually I don't know if intempestive is a good english word, I should have used innoportune (this one exists at least).

I will try your solution tomorow (since where I am it is late in the night and I don't want to rock and roll in other rooms and wake everybody up). The "electrical" origin of my problem has brushed my imagination, however it would be really odd (for the iMac has been here without any problem for the past 8 months). Plus, having to pay 20 dollars for a surge protector to resolve a problem that popped out of the blue, I feel bad.

Eventually, the Apple Store solution is indeed something to try, but hey everything else works normally and it seems like a little problem. I'm glad there is an Apple Store in my town.

Neurotically yours,

Uzume.

Yes I have something connected, a sympathic Western Digital Hard drive.

I'm going to eject it and see what goes around, but you know it's been plugged for 8 months (since I'm using it only as back up).

I'm glad I used a paleonthologic word !

Hi again,

as I supposed, disconnecting the external hard drive had no effect.

However, I am experiencing some new phenomenons.

- When I switch my iMac on / reboot it, there is a Finder window opened on the MacOSX folder

- Every minute or so, there is somekind of refresh or reload of... everything that is on my desktop. I mean, it's like... huh... hum, how to say. I have a dozen icons of .pdf or .docx or folders, and the -all together- disapear and reapear in a second. This is really annoying.

I'm beginning to feel like punching through my screen.

I'm going to look for a way to restore to the past week, if something like that is possible.

However, if any advice is passing by, please feel free to knock on the door: I have cookies.

Oh and another weird thing, I launched a movie, and I was asked if I was really sure to use VLC.app which was "a new app I've never used".

Huh, no, it's not.

On my mind, the last "uncommon" thing I did was installing a program called "Startup sound" which is supposed to control / supress the ... Startup sund.

First thing, it doesn't work. Second thing, I installed it 3 or 4 days ago.

The mystery continues...
