Free screen grabber

Look for scren hunter 5. Set it up to use prntscrn button to deignated folder, and file name, auto numbers and save as Jpeg then set it so it only makes a sound when pic taken and your set, Oh and set it grab active screen only that really helps when you have 2 monitors only then takes snap of the one thats active (selected). Then select the standby button will minimise ready for taking snaps.Happy snapping
