QuickTime 1.6 bugs are popping up all over. Jon Pugh <firstname.lastname@example.org> 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.
Set Per-Folder Views in the Finder
Tired of navigating to a particular folder and having to switch to List View every time? With Finder in Leopard, you can set viewing preference for each individual folder. Just navigate to it, and set the view the way you want (Column, List, Icon, or Cover Flow). Then choose View > Show View Options (Command-J) and in the window that appears, select the Always Open In... checkbox.
