[bppanwar]

New the version 1.0.12 of Cboard, the import of OBZ file from coughdrop is working well however the import from Cboard from one user to another is not working. Please see the details below.

1. After exporting the Board from Cboard in OBZ format when the other user is trying to import, the system brings the error message. The error message is in a black screen with a lot of codes.
   

2. Importing the board in the PDF. The current layout of the communication board in the PDF file is not in line with the board standard. It should be printed as
   . The label should be inside the box of the symbol.

3. The Button label for Import is written as 'Restore' which should be consistent as the Button label in Settings and the window title. Please replace 'Restore' with 'Import'
