This question was posted in response to the following article: http://helpx.adobe.com/indesign/using/generate-qr-code.html
There seems to be a problem with the QR generator widget. If you make an email QR, and then try to delete it and make any other type, it seems to get stuck in email mode and you can't change it after that. Even if you scrub the file, create a new file and try to create a QR, the old values stick, and you can't change it.
Is this an "oops"???
