  1. If memory of the device gets full and try to add new project, it will display error message with error code. You have to delete prior project and have to add new project.
  2. If you merge multiple projects data (fonts, Images and Image Lists) and run all into device, it is not necessary to display each script file of the respective project. It will display script file as per the “Sequence” of the name. So it will be displayed combination of the multiple projects script files.
