(note: This is the second time I've posted this. Usenet seems to be broken on the machine I used to post, and I haven't seen this article on the net. Sorry if you've seen it.) I just installed system 4.0 on my Mac Plus and I have some questions. If I make an application the start-up application and reboot the Mac, when you try to run Chooser or the Control Panel (from the start up application), it doesn't work (files not available, when all the right files are in fact on the system disk). If you start with the Finder, or quit from the start-up application and then re-run it from the Finder, both Chooser and the Control Panel work. I have seen this same problem with the 3.2 version of Chooser. My questions: why does this happen, and is there any preflighting my application could do when it ran to avoid inconveniencing the user in this way? Also, while the Installer worked fine, all the moving that it did completely fragmented my system disk; access times to the disk were really long. A good solution to this problem is: 1) Use Installer to update your system 2) Move the system to another disk 3) Delete the system on the system disk and then move the copy from the other disk back to the system disk. This way, you stand a better chance of getting contiguous blocks which speeds up access. Better yet, move everything off the system disk and re-initialize it. --------------------------------------------------------------------- Bob Heiney c60a-3eb@lemon.Berkeley.Edu c60b-hd@buddy.Berkeley.Edu "To stay young requires unceasing cultivation of the ability to unlearn old falsehoods."
