Hi William,

Can you tell me what version of Textual you're running when you get the above error? The required version is 0.1.18, as specified in setup.py. Anything later than that will give you the error you see. This code was written several years ago, when Textual was still just a baby :-) ... the version I used then was deprecated not long after my code was written, and I never got around to updating it.

Regards, Jeff
