[TxMt] error with "Documentation for current word" in Python bundle

[Christopher Brewster]

How do I get the "Documentation for current word" to work.
Currently I get the following error:

Traceback (most recent call last): File "", line 8, in File "/Library/Application Support/TextMate/Support/lib/dialog.py", line 12, in dialog = os.environ["DIALOG"] File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/UserDict.py", line 22, in __getitem__ raise KeyError(key) KeyError: 'DIALOG'

UserDict.py does exist.

Thanks,

Christopher
