In addition to being able to test the design right then and there, you can also draw with the new cursor to see if its 'hot spot' is in the right place. Integrated test area: Along RealWorld Cursor Editor's left side panel you'll find a testing area where your mouse cursor is temporarily replaced with the one you're designing. RealWorld Cursor Editor provides all the tools you need to modify an existing mouse cursor or to create an entirely new one from scratch.
