By the way, this week's Macintosh Weekly Journal has the first part of a two part article on MacsBug for non-programmers. If you sign up for a two-week free subscription before Monday, you will get this issue as well as next week's issue with part 2.
MacsBug 6.5.4a4 is now available. Changes include the merging of some dcmds, enhanced video display capabilities, text color capabilities, some fixes. (Thanks, Chan Lee Meng and Alexander Remington.)
