Press the hot key (Ctrl Alt PrtScr) or click the screen capture scrolling window icon and either move your mouse over to hover on the scroll bar, or wait for the red border to show up on the content window and then move your mouse over the scroll bar.

When you want to capture a scrolling window, first scroll to the top of the window, or scroll so the location you want to start capturing from is at the top of the window. Capturing a scrolling window is not really intuitive. Roland asked about how to capture a scrolling window just over a year ago and nobody replied to him.

I really like Fast Stone screen capture, and on the whole find it very easy to use, but for one thing which is really not well documented and took me quite a while to figure out.
