So I just updated to Mac OS X 10.6.3, and ever since I upgraded, when I use Safari, after around 3 or 4 minutes of browsing, it will just freeze on me. Sometimes it's quite severe where I have to Force Quit the application and relaunch it. It's getting quite annoying now. Anyone else have this issue on 10.6.3? I'm using a 2007 model black MacBook.
