Press Print Screen to open Spectacle. In the "Area" dropdown, select "Window Under Cursor". Click "On Click". Click "Take New Screenshot." Click on another window to take a screenshot of it. Save the screenshot and exit Spectacle. Then press Print Screen to open Spectacle again. "Area" will still be set to "Window Under Cursor" but "On Click" is no longer checked. (The "Delay" field will also retain whatever value you set, but "On Click" does not.) I also tried closing Spectacle, editing ~/.config/spectaclerc, and changing "waitCaptureOnClick=false" to "waitCaptureOnClick=true". Then when I run Spectacle again, "On Click" is not checked, and it also overwrites that line in spectaclerc and changes it back to "false".
I believe I fixed this in 16.04(.1?) Which version are you running?

Yep, how preferences are handled was completely reworked in 16.04. This has been fixed for a long time now.
Uh... I'm confused. If it's been fixed for "a long time now," why is it still broken for me? I installed 16.04 only a month ago and all my packages are up to date.
This was fixed in Spectacle version 16.04.0, not Ubuntu version 16.04.
