screen shot in full screen causes unresponsive window

Describe the bug
A clear and concise description of what the bug is.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

when I go to screen shot something in safari and have set to it edit in btt(easiest) it will freeze up the editor if I go to save as and put the screen shot in a new folder, then I have to force quite btt and restart it to get back up and running. I think it is because the popup window confuses the full screen deal in macOS
