Hi there
Ever since we went to Mountain lion, I have had problems with numbers slowing 
down big time on large files. I have Faillone the one thing that helps a 
little. I turned the mouse follows voiceover cursor off. I had it on, And I 
have found that it makes a difference. Maybe I should see what happens if I 
turn cursor tracking off as well, and see if that makes it even better.
