Home Forums Mac Software Mac Operating Systems Mouse freeze

On each start-up since I installed Snow Leopard the cursor froze. I had to force quit and restart, then the the mouse/cursor function is fine. I have only started the machine twice after being off for hours; maybe this quirk will go away, but I doubt that.Any idea why I now have a freezing cursor syndrome? That seems to be the only problem so far with Snow Leopard. Dave

It's a whole new pussycat with no history, so let's try to make some...

First thing I'd do is boot from my install disc and run Utilities>Disk Utility>Repair Disk.

Alternatively, or additionally, you can run the updated version of DiskWarrior if you've got it.

Let us know how you make out.

I had that problem in the past and the usual remedy was to unplug the mouse (and/or the keyboard, if it's plugged into the keyboard) and reconnect it. It's certainly harmless to try.

Thanks for the quick reply. Re: Artie505 ideas, I do not have an updated Disk Warrior, I will try the Util>Disk> etc. as a second choice. Re: Jon, I will try the unplug/plug trick first. There is another possible explanation. After setting up Snow Leopard yesterday, I made a change in the mouse settings(at the request of the other user of the Mac)that turned off the function of the scroll wheel that would bring up Dashboard. It is annoying when it happens by accident, so I don't really need it. I have now reset that function. I turned off the Mac for an hour or so and when I started it this time, NO cursor problem. I don't see why the change in that setting would cause a freeze, but time will tell. I will hold off, see how it goes and then try your both suggestions. Thanks, Dave

Are you using a third party mouse (or keyboard) ? If so, does the problem continue when using the Apple mouse/keyboard?

If you are using a third party mouse or have installed software that modifies the mouse's behavior, it may be that an updater is required.

And finally, is the mouse connected to the keyboard, computer, or hub?
(I'm just wondering if your mouse is getting enough power.)

Dave, Hi.

That you've said you turned off the function on the scroll wheel which brings up Dashboard makes me think (I'd bet) you're using a Mighty Mouse, right?

The Mighty Mouse is a terrific invention, I love it, BUT. The first thing I did was to disable those side-buttons which bring up Exposé. Depressing the scroll button brings up Dashboard which I use many times a day now that I've customised it......anyway, the Mighty Mouse does need cleaning now and then or you'll get exactly the symptom you describe. The other common symptom is you can scroll up but not down or vice versa.

Disconnect M.Mouse (I presume it's wired but it makes no odds) and hold it upside down on a clean sheet of paper. Rub the scrolling wheel hard on paper and run it about in all directions. Reconnect to Mac and away you go again.

Nowt to do with Disks, Disk Warrior, Leopard, or any other hardware/software thing. It's just the mouse doing what it does. IME.

Hope that helps, best wishes

DW 4.2 was released a day or two ago; the update can be d/l'ed here.

looks ok. be sure you have your original CD and a blank CD handy. It won't update the app, only make you a new cd. (from which you can drag off the updated app)

I've run DW v 4.2 already; it is definitely quicker than was v 4.1.1.

(PS: Those first two screens that I once mentioned would not display [because of the absence of QuickTime] when I ran DW from either my BootCD or bootable flash drive now display.)

Quick Update: I have replaced the Mighty Mouse with a cordless Logitech mouse that we used before we got this iMac. I have had no start-up freeze of the cursor since the switch. Will see if the luck holds! I have no idea why the change would solve the problem. Time will tell. Thanks, Dave

Thanks for getting back to us Dave, I was getting worried about you.

The reason your problem was solved after switching the mouse is as I surmised in post no. 2462 higher up this thread.
