Sweet!!!!!
Beta4 seems to have resolved some of the errors that I was seeing.

In particular
Code:
ERROR: ERROR: Unhandled exception
TypeError:argument 1 of QAbstractitemModel.createIndex() has an invalid type
Traceback (most recent call last):
File "calibre\gui2\tags.pyo", line 130, in parent
Type Error?: argument 1 of QAbstractItemModel.createIndex() has an invalid type
Thanks!
I notice that in Preferences/Conversion if "Remove spacing between paragraphs" is set, it is not set when you go to "Convert E-books/Look & Feel". Should it not be maintained if it is a Global Preference?
Thanks!
