The barcode reader I own enters new line at the end of the barcode (code 13) and if the mouse pointer is above a button it will press it before adding the product.
For example I put with the mouse *product 1* and then if I scan *product 2* I end up with 2 x *product 1* and 1x *product 2* (the mouse is still over *product 1*).
To avoid I have to make sure that the mouse pointer is on the empty area before scanning a product. This doens't happen if I use barcode scanner which doesn´t put new line at the end.
How can I fix that?
