The customer runs a simple app on his Win7 Pro PC out in the warehouse. It just sits there waiting for data from barcode scanners and scales. Everything is fine until it loses focus now and then. Usually we can't see anything causing this, so my guess is that it is something going on in Windows or in another app, "behind the scenes", but still somehow taking the focus off the app they are trying to run.
I have removed a few things that came with the computer that might normally pop up and ask questions. Literally nothing is still activated in msconfig. They ARE running Norton Internet Security, but like I say, I have never seen it--or anything else--up on the screen when this happens, so I don't know what is causing the loss of focus.
It is a big deal for them, because when this happens, their scan and weight data is not going to the app, and if they don't see this happening on the screen, the data is lost. So I wonder if there is some type of Windows setting that will always insure that the warehouse app keeps focus, no matter what else might be going on in the background. Or, is there some other way to solve this annoying problem? TIA
