I turned off the "Automatically Save Screenshots" option in the snipping tool settings and then the pop up of the snip I just made started showing up. I turned the auto save back on and the pop ups went away. I am thinking that since it is already "saving" the snips somewhere it decides to not let it pop up.
This worked for me and has resolved the issue of the New Screen shot not appearing in a new window.
I have turned OFF "Automatically Save Screenshots" option in the snipping tool settings and it now brings up a window with the new Screenshot, ready for editing, saving or copying.
Perfect
Thank you
