Trying to capture QR codes using application QR Journal 2.0 or using Web QR Internal Camera will not scan QR code when holding QR code in front of camera on iMac. QR code shows in app windows so the camera sees it but will not complete scan.

I know QR code is good because I can take picture of the QR and import into either of the above and it launches web sites.

Is there something wrong with FaceTime HD camera? It works in Photo Booth.
