As with all updates, some people reports issues after completing the installation. As usual we would like to remind you to backup your system priori updating. With Mac OS X 10.7.3, it seems that there is something wrong for a number of users (cause remains unknown) leading to a buggy and unstable system after reboot. To our knowledge, re-applying the Combo 10.7.3 update will fix the problem (as it already did it in the past with previous updates). If you happen to have a system so instable that you will not be able to download the Combo update on the affected Mac, then get a USB stick, install the update on it using another Mac, then apply it to the unstable unit.
