I got a Macbook a couple of weeks ago, everything works fine except one thing that bugs me. Some sites that are heavy on flash (banners, ads, embedded youtube videos), make my browser lag quite a bit. For example this site: http://www.purpleandbrown.eu/?m=200610 , when I try to scroll down the page, it feels laggy and jumpy. Ive checked this site on a 3 year old dell laptop running winxp and Firefox and it runs smoothly. Is it because of our version of the flash player for os x? Any ideas?
