Hello. Recently my Mac starts to act weird. Sometimes when I switch between a web page (Safari) and text editor (BBEdit) the page would jump up and down for a while then it will settles down. I am not sure why, that happen and how to stop it. And when I try to highlight certail words, it will jump up and down again. Very annoying! :0 Any suggestions? Thanks.
