What kind of problems? What’s your setup?
When I try to open certain sites, such as the WMAL one, it jumps around and flashes and doesn’t load, as if I were hitting the reload button continuously, although I am not. I did a little snooping around, got onto the site by finding a link that didn’t have any moving graphics, and at one point got a message that said I didn’t have cookies enabled, which is not the case. Anyway, it is annoying. It ticks me off to do something recommend by Apple to make performance better, and it ends up being worse.
