This program worked great the first week I had it, but now it will never scan barcodes. It will scan maybe 1 out of every 10 barcodes. Is this normal? It's not scanning them and then telling me the product isn't found, it just won't scan them and sits on "Scanning barcodes, please wait." And I see tjhe little green dots running up and down the bars. I'm holding my hand as still as possible, focusing on the barcodes, and even try moving the camera in and out. I've even uninstalled and reinstalled it on my Droid X. What could be the problem?
