The update looks good and fast too..graphic performance in RAGE i tested seems improved,no bug or beachball until now thanks god.
The "Reopen windows when logging back in" settings is still crap. It actually remembers your last setting prior to a restart/reboot. So if you happen to check the option before that, it will stay checked on your next restart/reboot until it is unchecked again. It is not permanently unchecked for every restart/rebooting.
Nah... Even with a clean install of 10.7.3 the first thing I see was a bug - Finder menu disappeared... Can you imagine that...? This is from a clean install. With 10.7.4 and that restart bug, I don't wanna waste my time anymore with crappy Lion and quickly downgrade back to SL...
