TabError: inconsistent use of tabs and spaces in indentation

Hmmm- that's a bug in the code,



Could you try installing the attached version of Modify

I wonder what your ePub has that causes it to follow that code path. Let me know if works (it works for me but I wasn't running up against the error), I have asked the person who changed the code last (Rev.Bob) to take a took at this thread, he is the person most familiar with code.

Interpreted languages that use code indentation to define scope ain't one of my favourite things - I'm more of a schnitzel with noodles sort of guy
