I have had this problem in the past and then it seemed to go away. I have tried resetting safari but it hasn't helped. I have almost had it with safari altogether. It sucks on the iphone, although it isn't near as bad since the last update, and this stuff that keeps happening almost renders it useless, esp. if you are trying to show someone else a page. I have no clue what it could be. I am running safari, itunes(nothing playing), and software update on a mbp 2.4 with 2gigs of ram and it still does this. If anyone has any suggestions or ideas please let me know, as I would really like to stay with safari. Thanks.
