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.
