Ok, first, download paint.net from http://www.getpaint.net
Next, download a plugin called alpha mask here : http://forums.getpaint.net/index.php?/topic/1854-alpha-mask-import-plugin-20/ and install it.
Then, go to "Effects" - "Alpha mask" and check the boxes with "Invert mask", "Mix alpha" and "Copy from clipboard"
You're done! Yea I was like WTF? When I tried this too. No more stupid "fuzzy select tool" for me
