Just a real quick one - I recently had the need to do a scrolling screen capture, which sent me on a forage through the internet that led me to TechSmith's SnagIt. This software is very clever and at $49.95 I decided to purchase after my 30 day free trial. It's really useful for me at work where I often put together how-to documentation, and I think it'll also be a great help for this blog, too!
Thought I'd share the love. If you ever need a handy screencap tool which includes editing capabilities, scrolling capture, live links in screen captured PDFs... at least give the trial a go.
