That's what I observed when I first patched. It froze a few times immediately, then it was as if the system just kinda settled. Is it possible the software continues to update files after restart? I dunno, but I have been fine for days now.
That's odd. Same is happening to me. My machine never froze as much as others machines (during normal activities) it seems. However, before 1.3 I was able to make my machine freeze using the leopard screen savers while rapidly mousing over the magnified dock. Updated with 1.3 and I still was able to make it freeze. The past couple of days my comp has been flawless (pretty much - safari has started to occasionally crash) though. I have tried the screen saver and mousing "test" and it has passed everytime. I even tried doing this test with WoW and iPhoto in the background---still no freeze. Now, this is either good or bad news --Good if it never freezes again/ Bad if it randomly freezes because I won't be able to reproduce the problem to a genius anymore. I will keep you guys updated.
