I bought my MacBook Pro 13" 2.4 GHz in late April (new version). I have no added third party software. Everything worked fine until I did the Safari 5 update. Then web pages would freeze when opening for about 3-5 seconds. Then the page would finish opening. I have also updated OS X to 10.6.4 after this started happening. It did not correct the problem. I experienced this at several locations, including the Apple store when doing one-to-one classes, so I know it's not a problem with my ISP. Anything I can check into before I take it to the Apple Store? Have others had this happen?
