Hey, so I'm looking for some good software (preferably free, or at least cheap) that can automatically take a screenshot of a specific window. Like, if I have a window open, and it's not full screen, I want to be able to screenshot just the window, and nothing else. I'd just use Print Screen, but windows in XP are curved on the upper corners, so I can't avoid also screenshotting what's behind it a little bit, at least not without some serious attention to selection.
I'm going to be using this to create hundreds of screenshots, so automating the process as much as possible would be great.

Important notes:
* You will need to install python ( http://python.org/ ) PIL ( http://www.pythonware.com/products/pil/ )and Sendkeys ( http://www.rutherfurd.net/python/sendkeys/#sendkeys )
* Copy and paste the code section into a new text file, and save the file as pyscreencap.py, in a directory by itself.
* You may need to turn off Numlock. Windows is Weird.
* Copy-paste is unlikely to work correctly while this program is running, as I'm using Alt+Printscreen to make this work.
* When switching between windows, it may take a few seconds for the script to switch to the new window. I don't know why.
* If your windows have rounded edges, the screenshot will include whatever's behind the window in those few pixels. If is a problem, change your window style to classic.
* If you keep getting "screenshot not acquired" errors, hit Print Screen. This should be fixed now, though.

I mean, good job and all but Microsoft seem to have this one covered?
This one automates hitting Alt-Printscreen, and saves everything to a series of files. Hitting alt-printscreen, pasting into paint, then saving gets old rather quickly.
