If you're feeling adventurous and helpful, I'd appreciate the following favor:

Download this:
http://media.pyweek.org/dl/4/BDG_07_04/wtipd_dos.exe

(requires Windows and a non-poky net connection; it's 7.1 MB of download)

If you can do that, the next step is to run the program. You should see some circles, not unlike the picture above. If you don't get the picture, and just get a blank screen - I want to know. If the program just quits, or crashes, or spits arcane crap to the DOS box, all of these things are good to know.

I'll probably make another version soon (?) which may give even more information about what might be going wrong, if something does go wrong.

Thanks in advance to any crazy people who try it.
