Screen capture app

I needed a screen capture app 'cause I'm having some problems with Dolphin Mini. So I d/l'ed "Screen Capture" because it said that your phone didn't need to be rooted. BUT, apparently you can't just load & go with this app, either. It mentions something called Android Debug Bridge. There's nothing like that in the Market. Is it built into the phone?

It's so annoying that even tho an app doesn't have to be rooted it still needs an extra bit of arcana to make it run correctly. And the Dev's first language isn't English so his instructions, along with Chinese ideogram instructions, is somewhat confusing.

Does anyone have a screen capture suggestion that also doesn't need to be rooted and may be easier than "Screen Capture"?
