Awesome ScreenShot Capture is Not Awesome

So I downloaded this app called Awesome ScreenShot Capture yesterday and it worked for me. One of the images is in a previous post. But today when I try to take a screen shot just of what I am looking at and not the whole long page it does not work. The site I am trying to capture a pic of is amazon a particular book title. I was going to post some commentary but that doesn’t seem to be likely. I am going to send this to the company and see if they can justify wasting my time or not, I kept clicking over and over and trying different things to see if it would work for a long time. Your software should be simple to use guys not giving me these pain in the neck problems.
