b. LaserWriter crash According to an Adobe tech support document: When you select the Apple LaserWriter 8.4.x printer driver and then click Setup in the Chooser, a Type 11 error or freeze may occur if Adobe Type Manager (ATM) Lite 4.0 is installed (spotted this on MacInTouch). This is an issue we have covered here on several previous occasions (such as here).
c. Richard Ford talks The comments by Richard Ford (of Apple Computer) on the future of Open Transport and related matters (as described in an edited transcript on the MRP) is well worth reading. Among other tidbits, Richard reveals that OT 1.5 is officially dead, although a smaller bug-fix upgrade to OT 1.2 is still on the way.
