There are various tools available, but I prefer to use the Prt Scr button on my keyboard. To do this:- Press function button (or a list with an arrow on some keyboards) at same time as the Prt Scr / SysRq button. Open MS Paint. Ctrl V (or Edit Paste). To get from Entropia to Paint you may need to Alt + Tab which can cause Entropia to crash; an alternative is to run EU in Window mode which is accessible from the options button on the login screen.
