Tried half a dozen screen capture apps today trying to get full page captures (like entire page in browser...not just active window visible onscreen).

After several hours of having other apps kill my wimpy little PC, I tried SnagIt and had all my full page captures in less than 10 minutes. Did not have to access the user's guide, say nice things about my processor, or even cross my fingers.

The PNG files it produces are 200-400K (for a fairly scrolly page). Even setup a profile and hotkeys so I could do this again more quickly (still didn't have to reference the user's guide).
