[Koha] barcode scanner

I found a wedge barcode scanner in a drawer yippee! odd thing is that when I zap the barcode it automagically issues a carriage return which blanks out the fields and reloads the page because all of the other REQUIRED fields are not filled in yet...and appear way down on the page...i.e. adding members is there some method of preventing this from occuring? or do I just tell the volunteer lady to deal with it and don't scan until AFTER you enter in all of the other fields? --Huck
