While I was reading about Snow Leopard’s old version of Flash, I also learned that Snow Leopard doesn’t preserve your screensaver/energy saver password protection settings from Leopard. If you upgraded from Leopard to Snow Leopard rather than doing a clean install (or possibly if you did a clean install and then migrated settings from your old Leopard installation), you’ll want to check your preferences on this.

My screensaver password lock was disabled after upgrading. Another change to my security settings without notification or permission? Some changes are necessary and difficult to migrate, but PLEASE tell me about things that affect my safety when using my computer.
Odd thing for Apple to overlook.
