When I save a project or an audio file with Spark, Spark LE or Spark XL 2.x under Mac OS 9, I get an error message saying: Unknown Error -5699
This following procedure will work with Spark, Spark LE and Spark XL.
The easiest way to fix this is to rebuild your desktop by rebooting your computer and holding down the Alt + Command keys on your keyboard. Keep them held down until your desktop appears.
You will then be prompted to confirm rebuilding your desktop. Click "OK" to confirm. After the desktop has been rebuilt, Spark will no longer display this error when saving.
