Versions of ForScore prior to 3.0 had the option to work with barcode scanners that do not end each scan with a carriage return.
Because of the amount of confusion that brought about, that option has been removed.
You can no longer print barcodes "with carriage return" (the ones that showed an asterisk next to the barcode).
You MUST configure your barcode scanner to add a carriage return after its scanned data.
