I was only able (or rather, willing) to do the cool, long screen captures on my previous post because of Easy Screen Capture And Annotation—a nice and full-featured software that allows you to capture the entire content of a scrollable window, among many other things.

It’s shareware ($30), but you can use it for free without any limitation other than a welcome-nag and a red-watermark when saving your image (which can of course be easily bypassed by copy-pasting your capture to another graphic-editing program). Very useful if you ever need to do serious scren-capturing.
