I am writing up a demo script and I want to capture some images. So I press my trusty PrtScn keyboard button and nothing gets added to the Clipboard. So I think well that is odd, but maybe I have some background process intercepting PrtScn. So I launch the Snipping Tool. That tells me the content I am capturing is protected and so I can’t take a snapshot. I ask myself what is so protected about the Properties Window in Visual Studio?

It turns out that the reason neither of these work is that I have a rights protected email open in Outlook. So even though I am not screen capturing that email, all screen capture software is disabled until I close that mail.
