I am trying to take a screenshot of a selected area. The Wiki here: https://wiki.debian.org/ScreenShots
says I can use "take screenshot" from the menu. On my menu I have "screenshot" but it doesn't work (although I think it used to) it just displays a tiny box which I cannot make larger. Assuming the command line is: gnome-screenshot -a -d 20 I tried this but the mouse pointer immediately changes to a cross and I cannot change tasks, so all I can do is photo the terminal window. I think something is broken. Maybe there is another utility?
