I suspect that this is because it is trying to execute the preceding code in between every key, and the program thinks that the keys are being pressed too fast. If this sounds legitimate, how can I work around it? If not, what could be causing the screen to lock up? This is a very urgent problem, as this a very high volume screen and the problem is causing serious delays. Thanks in advance for any help you can give.

Yeah, I was aware of that, but I had to learn that the hard way also. I don't think it's causing the problem. Another hint... when scanning in the SSN, the computer issues a series of beeps, like the ones you get when you hold a key down in DOS for a long time. I'm guessing sort of a keyboard buffer overflow warning, but it does this even when the screen doesn't freeze up, and the data gets into the field just fine. I'm getting flustered here.
