I am unable to take screenshot / printscreen of my eclipse menu.
when I try to take screen shot of the eclipse menu file -> new -> Android project my print screen is not working.
when any of the menu is in clicked mode(i.e file,edit, run, ...)
Note: I am using ubuntu linux
Yes, any keypress will dismiss a menu.
General workaround to this issue is to delay the actual screenshot action.
In Gnome you can issue this command in command line:
$ gnome-panel-screenshot --window --delay 5
and it will take a screenshot after 5 seconds delay - of the window that is current at that time
