The "Cannot close ..." dialog appears when &xshutdown; encounters a non-Presentation Manager (PM) session. This includes &os2; and DOS text sessions and &winos2; sessions, be they full screen or windowed.

Since there is no predefined way of how to close such sessions, &xshutdown; prompts for an action here. The following actions are available:

Note that neither of these methods will save the data of the session. If you wish to have the data of a certain session saved, save the data of the session's application and close the window yourself now, which will also cause &xshutdown; to continue.

If the "Store these settings..." flag is checked, &xshutdown; will remember the selected action for all future sessions which carry this title. Checking this setting will add this session title to the list of auto-close items which are available in the "Auto-close details" dialog on the "&xshutdown;" page in the Desktop's properties notebook.
