To anyone who can offer me any advice!! I'm relativly new to macs having switched only about a year ago - and I've noticed somthing very strange. My mouse is often behaving erraticly, entirely ignoring the left or right clicking on applications (recent example, trying to close iTunes etc) but only when Safari is open. It then goes on to get worse, slowing the system down and then freezing it entirely. Ive done all the maintanance tasks recomended to me : Varify and repair permissions, cleaning logs etc but it hasn't made the slightest change. It's recently started happening on drop down menus too, but not when I have safari open! Ive backed up all my documents in case of a lashing question mark situation, and checked the S.M.A.R.T status of my drives which is ok. Any other suggestions?! Any advice you guys can offer will be really appreciated. Thanks.
