Be sure that your current directory is writable, that both your current directory and the CD-ROM directory containing the record you wish to edit are in your DB path, and that your current directory comes before the CD-ROM directory in your DB path. When WAVE writes your edits, they always go into the current directory (so the current directory cannot be on the CD-ROM, since the CD-ROM is not writable). At a later time, when WAVE (or any other DB application) opens the record, it finds your edited version first, and doesn't look for the original version on the CD-ROM, provided only that, in your DB path, the CD-ROM directory follows the one in which your edits are stored.
