I've never gave comments here before but this software made me do it. I just switched completely to MAC OS X so i had to find a screen capture software once again. I have downloaded and downloaded and tried other software from this site. And by far InstantShot is the simplest and easiest to use. You don't have to select the software to capture screen, this software just sit at your menu bar without interfering Windows you are working on. Just press hot keys wherever you are and That's it! and it's FREE!
