Hopefully I can explain this, I have a php page that submits a form to itself. I am using a scanner to enter numbers from barcodes into a text field and then submitting the form. When I scan a unique number the form works fine. When I scan a number I have scanned before, a list pops up of the number scanned and then the enter selects the number from the list and form is unsubmitted. I have no idea what is doing this, but I run into the same problem with IE8 on winXP and the default browser on an android tablet so I am thinking I need to code something to prevent it. Any ideas on a solution would be welcomed.
