Superb work.

Now, just to recap, here are my current issues:
- I can't add formats and interpreters, since when I try to click "OK" or "CANCEL" it gives the same null result (I really mean "null" - nothing happens at all when I click those buttons). On a related note, a "Browse" button would be useful here.
- Hey, while writing this post I managed to make it so the app doesn't start anymore, don't ask me why...
...the only thing I think I did out of the ordinary was accidently trying to open it while it was already open. Now everytime I try to open it says:
---------------------------
Errors occurred
---------------------------
See the logfile 'C:\Interactive Fiction\Tools and Interpreters\grotesque-0.9.1-win\grotesque.exe.log' for details
---------------------------
OK
---------------------------
And the logfile:
Traceback (most recent call last):
File "grotesque", line 3, in <module>
File "grotesque\main.pyc", line 776, in main
File "grotesque\main.pyc", line 80, in __init__
File "grotesque\main.pyc", line 245, in load_library
EOFError
And I get this even if I delete all the files and unzip them back. That's pretty weird.
