mouse cursor disappears and reappears in middle of screen

Switching USB ports can also help rectify issues on USB devices.

Check if recharging or swapping out its batteries can end up making a difference.

I'm going to go fix permissions right now, but I was hoping somebody here could ID this and help me figure it out.A wireless or Bluetooth mouse that’s about to run out of battery can also stutter and pause in Windows 10. It's a new 15' MBP 2.2 Ghz, 4GB Ram running Leopard 10.5.2 with all updates (even the recent keyboard update).Ī search on this brought up someone else on another board with the same problem, but then the issue got clouded with discussion of dual-monitors or external displays (neither of which I use). This has never happened on any machine I've had before, but by all indications it's a software problem, nothing to do with the hardware. In fact, I only get a cursor once I click on an app and either launch it or bring it up from being minimized / hidden. If I go down to one of my hot corners, the associated action still happens (in my case sleep the display / activate screensaver -how ironic ), and if I roll over the dock I can bring it up and magnify the icons as I roll over them.

I know the cursor is still there, but it just can't be seen on screen. Sometimes (not always) when I comeback to my MacBook after it's gone to screensaver then display sleep (though not full system sleep) the cursor is invisible upon wake. Here's a weird problem I just got on a new (refurb) MBP.
