Don’t try Code 39 or it crashes – Universal Scanner Review

I used to use RedLaser and then ZBar to scan bar codes at work, for inventory. It was easy - all I needed was a simple way to grab the code save it for later. New version suddenly started to crash every time I scan a Code 39 bar code. What’s worse, it saves the code, so now it crashes instantly as soon as I open the app. I can’t clear the code or use it for anything else. I do not need the scanner to look up info on the code. All I want it to do is scan, then give me the option to take an action - otherwise, how do I know any given code is safe to scan?
