I ran updates last night and installed the 2007-004 security update, and an update for Aperture to 1.5.3.. Now when I turn my MBP on, the system will show the desktop, menu bar, and dock.. but it takes an additional 30-45 seconds to show the desktop icons and the menu items in the upper right hand screen, as well as doesn't allow me to do anything until it shows all this stuff. Just kind of hangs for this time period. Never did it prior. What is up? What should I do to remedy?
