Mac OS X 10.4, 10.5: Relaunching an application after it unexpectedly quits
Summary
If a Mac OS X application unexpectedly quits, an alert appears that lets you report the issue to Apple (see "Want to send a report?" below) or try to reopen the application. This article applies to Mac OS X 10.4 or later.
Products Affected
Mac OS X 10.4, Mac OS X 10.5
For example, you may see this dialog in Mac OS X 10.5 (a similar dialog appears for Mac OS X 10.4 with a Reopen button instead of Relaunch):
If you click Reopen but the application unexpectedly quits again, you will be presented with a similar option to reset and relaunch (reopen), shown below for Mac OS X 10.5.
The "Reset and relaunch" option resets the application's preference settings to a default, then opens the application again. Note: Some applications, such as Mail, may store a lot of information in preference files. You may need to spend some time reconfiguring your application's settings if you click "Reset and relaunch".
