You have to first paste it into a graphics program and then save it.
Try using Paint.
Obviously Thunderbird does not paste graphics, and I'm assuming B11 is
having the same issue. But Microsoft outlook does, and I know Word
does. I used it all the time to cut&paste screens. I guess the 'paste'
now hinges on the windows program being able to accept a pasted bitmap
inline with text.
Still if you made a shortcut to the clipboard, 'clipbrd.exe' then you
can just save and then attach to messages/mail.
