A new, nut-driving symptom is plaguing my mac of late. My cursor will freeze for a few seconds... sometimes it even disappears. Didn't we used to have a cursor-disappearing bug back in the early days of OS X?

I can't even begin to figure out where this one is coming from. It feels like the computer is stalling. I don't know if it's a hardware problem or an operating system problem at this point.

I have been getting this too. I am not sure if it is my mouse dying or not. It doesn't disappear but just stops moving. Un/replugging the connection brings it back to life.

It might be a USB issue. I don't have any native USB 2.0 ports so I have to rely on a PCI USB 2.0 card. It was been really wanki the last several OS updates. I even broke down by getting another brand card. It just made it worse.

yeah, I noticed that unplugging and plugging in the mouse sometimes cures it temporarily.

Oh man, all I need is a USB port to go south on me right now.

thalo are you still having this issue.

It has not stopped for me. It seems like a cursor rendering issue. As when mousing around when the cursor changes to a different icon when rolled over something it gets hung up. Sometimes temporarily but sometimes permanently. Unplugging then replugging in the USB connection corrects it for me. My mouse is really old now I have noticed sometimes the infrared light goes out when it happens but not always.

It does seem though this started at X.5.5. The same time the PCI USB 2.0 card went haywire. I think I said before whenever I download images with Imagecapture the files download in a total random order not in sequence. You can watch them down load as a thumbnail window with the file number underneath it. This is why I said it may be a USB thing. But you have a wireless mouse no?

X.5.5 PowerPC thing too.

Rico, have you tried hooking up the mouse and keyboard to the inbuilt USB-Ports of your mac? I also use a USB 2.0 Card for certain stuff (Wacom, USB 2 Sticks, Webcam) but my keyboard and mouse are plugged into the standard inbuilt ports. Never had trouble.

Still having the issue. I have a wired mouse. It's a one-button Apple Pro Mouse.

I tried swapping mice with Seabiscuit, that seemed to be better for a while. Now it's back to bad.

Also experiencing some slowdown in performance. Particularly with Quicktime and Flash.

Don't ask questions. Just try this. If this is happening after waking from sleep, go to the mouse control panel. Open it. Switch to another panel. Quit system preferences. See if this helps.

I have finally gone back to my old Wacom tablet set up. What a pleasure. The Logitech mouse I was using was getting old. I think it was beginning to fail. The IR sensor on it keep going out.

I always like the Wacom tablet set up. I don't know why I had stopped using it in the past. No cord and no batteries to worry about for the mouse.

I don't know how I was managing with the faulty Logitech mouse for so long.

Oh and smithz yes I was using the keyboard plugged into the motherboard USB port. The mouse was plugged into the keyboard.
