At least not every time something like this happens.
Yes, if crash happened during file write, B-Tree needs to be rebuilt. In OSX, journaling, if you enabled it, is tracking such problem and will automatically fix the out-of-sync file pointers. In OS9, rebuilt desktop was about the only thing you could do, besides crossing your fingers. But this is all about file pointer, and journaling will not ensure the integrity of the damaged file. But what you don't understand is that the file gets corrupted at crash is file being write-ready or during write state. System pref that you mentioned are not. Some of the app's pref are. Lucky you never owned such app. For example if you have audio/video editing studio, all the hardware pref under OS9 are write-ready until the host is closed. If crash happens, the pref most likely gets corrupt and app no longer functions. You were comparing with internet browser. Internet browser has no real time file I/O. You then were comparing with M$Word. M$Word creates invisible cache file to avoid file corruption at power loss but again M$Word doesn't write until you save the file manually, but auto-backup file will be corrupt if power failure happened when M$Word was writing to it automatically, just as PM checking email. Think about it. Any real time I/O application such as audio tools will corrupt project file(s) just as PM does if crash occurred during processing the file. To recap, if you expect email client to act as your favorite M$Word and internet browser, do turn periodic email check off, and download emails only when you tell PM to do so. Now back to your machine problem, did you take a look at system.log? Have you ran Hardware Diag? -- - Hiro [PROTECTED] <[PROTECTED]> <[PROTECTED]>
