Database is locked?

ChequeSystem is a standalone software that locks its database while running.

If you try to run a second instance of ChequeSystem on the same database simultaneously, a dialog will appear. You will then have the option to run the software in READ-ONLY mode.

When running in READ-ONLY mode, you can only view the information stored in the database. You cannot create or edit cheque, modify payee or other information, or adjust software settings.

If you are the only user of ChequeSystem on your computer and are not share the workspace with other computers, please check if you have accidentally double-clicked to run ChequeSystem twice.
