Yes I have the problem on Firefox and Safari and it frequently jumps back to previous screens whenever I am on any site, I can be filling in a form/writing an e mail/message/paying for something and it just jumps back to a previous screen, I then lose whatever info I had just put in
It does seem entirely random. I'm using a portable mouse that works on wifi.
The screen does not always jump on the arrow capital command but sometimes it does. I have also known it jump when pressing return
The only button the mouse has is a tiny on/off power switch on the back.
The mac isn't portable. It's a late 2012 27" screen. OS X, version 10.8.3
Processor 3.2GHZ, Core 15 with an 8g memory
And the back comes off the mouse to replace the batteries
Right David, done all of that.
On System Preferences Login items: itunes helper Application
On Finder Internet plug-ins nothing was in that folder or listed
David, done all that. Don't actually know if the problem's solved yet but the computer is working much faster. If the problem continues I'll get back to you. In the meantime,
