What are the minimum system requirements for running Scrapebox?

Scrapebox doesn't have an officially stated minimum requirements.  However generally speaking its not terribly taxing on a system.

It does require the Windows OS.  It has been tested on Windows XP, Windows Vista and Windows 7, as well as Windows 2003 and 2008 server.

Generally speaking I have seen it run on some pretty minimal systems and VPS, however when you want to run more then 1 instance it obviously begins to consume more resources for each instance you run.  Also working with larger files will use more resources.  So the more you want to use it the more powerful of a system you will need.
