Error Messages close automatically after 3 seconds is a problem for barcode scanning

With the patch that auto-closes the error message, barcode scanning errors now do not interrupt scanning.  Before, if I scanned a barcode that was not recognized, the error would prevent all other scans.  Now, if I have 10 items, if the 3rd item doesn't scan, I may not notice that 1 or other items did not get added to the check.
