QuickTime 1.6 bugs are popping up all over. Jon Pugh <email@example.com> reported on Info-Mac that he isolated a conflict between QuickTime 1.6 and Now Toolbox 4.0.1p that caused problems when resolving an alias that mounts a network volume. In addition, two companies that I beta test for have mentioned that QuickTime 1.6 conflicts with the latest betas of their software (and no, I'm not going to say who since it's not shipping software). Beware.
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
