If an application unexpectedly quits in Mac OS X v10.4 or later, an alert appears that lets you report the issue to Apple, or try to reopen the application.

Mac OS X v10.4, 10.5, 10.6

You may see this dialog such as this in Mac OS X v10.5 and later (a similar dialog appears for Mac OS X 10.4 with a Reopen button instead of Relaunch):

In Mac OS X v10.6 and later, the above dialog will reappear if the application unexpectedly quits again. The below dialog does not appear in Mac OS X v10.6.

Mac OS X v10.4 and 10.5 only

If you click Reopen but the application unexpectedly quits again in Mac OS X v10.4 or 10.5, 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".
