## SYMPTOMS

The Setup Toolkit function CopyFilesInCopyList() automatically presents disk change dialog boxes to the user when the next disk in the setup is required. This dialog box has OK and CANCEL buttons. Under certain circumstances, pressing the CANCEL button is ignored.

## RESOLUTION

There is no way to change this behavior. The disk change dialog box is managed by CopyFilesInCopyList(). The only way to avoid this behavior is to make sure there is at least one "vital" file on each disk.

## MORE INFORMATION

If all the files on the requested disk are marked as "non vital" in DSKLAYT, pressing the CANCEL button will cause the requested disk to be skipped and a prompt for the next disk to be displayed. The expected behavior is for setup to be canceled when the CANCEL button is pressed.
