Have to click twice for mouse to do anything

The problem isn't four years old, it's current. The fact that Apple hasn't resolved this is bad on them, not on us. I gave up using my Mac Pro because Apple wouldn't fix this. Now I use an iMac. Don't you want people to know about existing problems?

There is a nice person buried underneath your first post. Nice to hear from you. You seem polite.

Since the iMac 5K is less than one year old, there can't be any posts about it that are over one year old. This thread, where you are posting this, isn't about hardware, but is about the OS X operating system, which is 16 years old. If it applies to your current problem with OS X, then you may benefit from it.

No. This is a User-to-User forum. NOT a channel for talking to Apple.

There is "Contact Support" button at the top of this page.

Since two weeks or so i have a similar problem with my external logitech mouse.

After 2 hours work on my iMac running 10.6.8 some mouse clicks are ignored so that i have to click twice.

Thats especially nerves in a first person shooter :/

I'm thinking about switching to gentoo.

Glad I came across this discussion. I'm having exactly the same behavior with the mouse clicks. SOmetimes a click works, other times I have to click twice. This happened recently so it must be something with the last upgrade.

Same thing is happening to me. It is slowly driving me insane...

Same problem here, thought that upgrading to Lion would solve it but no.

Also, I've noticed that it happen after the macbook wakes up. Restarting or logging out solves the issue, but then at some other sleep in the future it would happen again.

UPDATE:

Actually I noticed this message in the console:

8/10/11 10:47:22.223 PM Spotify: Media key event tap was disabled by timeout

So I closed spotify and it worked...

ugh.. this is killing me.. I've had this issue since cloning my system across to my new MBP using superduper last week. the old lappie had issues, but this was not one of them!

restart has not helped, and i plan to do a clean install when i have time.

I experience the problem in Finder, Firefox, Journler... pretty much everything, really.. its almost like I need to give a button focus before it will accept a click, but that can apply to two link next to eachother on the same page!

Also, I've found that there is some kind of intermittent persistent-mouse-down behaviour happening, which i've seen in photoshop, keynote and finder, i believe. As an example, I could single-click a file in finder and move the mouse away, resulting in a selection box being drawn. If I Cmd-Tab to another app, i may not be able to use that app until i go back to the offending click-stealer (eg finder) and give it a firm click to trigger a mouse-up... this is my interpretation of whats going on.. not based on any technical background... I haven't had time to really document this bug, sorry.

I'm running 10.6.8 on a 2011 MBP i7 2.2g. This occurs for my trackpad, magic mouse and hp-laser-usb-mouse.

After examining my logs I’m seeing many references to FFhelper, and I realise that I installed Function Flip recently: http://kevingessner.com/software/functionflip/

It seems to work most of the time, but fails sometimes.. then it tells me its running, I stop the service, then restart it and it functions again.

I’ll be switching it off for a while.

Update: much improved performance with FunctionFlip switched off...

I’m also a longtime user of Better Touch tool and Launchbar, which have never caused a problem.

these messages occur most regularly for firefox and thunderbird.

Experiencing this too. I must say that clicking my trackpad often registers a click better than merely tapping it. Besides, BetterTouchTool does not particularly like Spotify...maybe some conflict in the background? However, also happens when Spotify is not launched...pretty annoying indeed.

Same thing here. Really annoying. Bought MBP and installed Lion hoping everything will be smooth. And there's this awful bug.

Sad thing that this thing isn't constant so neither can I get used to clicking everything twice nor show the bug to someone who could fix it (service center e.g.)

just make a clean install of Lion without using Time Machine to transfer your data. This way the bug will go away. I transfered all my data manually, folder by folder. And everything works great now.
