See if one of these 3rd party apps will work for you: 1. FastStone Capture 5.3 (last freeware version) It captures rectangular/active screen or area, freehand area, and also captures a scrolling screen.
3. ScreenHunter, which can do a scroll capture, but only on the Pro version, which is not free. Check "Activate Auto Scroll", then use "Capture Window Control."
