I need to write some guides for my development team on how to get some software up and running and would like to include partial screenshots. Are there any tools that are particularly good at this? Word is almost there in that I can easily paste screenshots inline with text, but I need the ability to crop the images and Word image manipulation is really painful. I'm somewhat biased against screencasting as I hate having to go back to a screencast for reference and sit through a bunch of talking. Are MS OneNote or LiveWriter any good at this?
Edit: Going to use the free Cropper tool (looks pretty polished and allows you to do screenshot and crop in a single step) along with MS Word. Couldn't justify paying for more software but SnagIt looks really good if you're going to spend money.
Edit: I didn't intend to duplicate this question but the accepted answer there covers the options presented here pretty well.
