"Note about insertion of citations in footnotes in Papers 2.2.23
(beta): thanks to Jonathan, we realized support for this only works
in Word 2011. I am sorry for this limitation. This is not something
we can improve upon at the moment, but we'll look into adding
support for Word 2004 and 2008 in a next update."
I have updated to Papers 2.3.2, which I use with Word 2011 but I
am not able to insert citations in footnotes. It looks like if the
citation is in the text it does create one as a footnote is the
right style is used. But if the citation is in the footnote and it
tries to format citations, the footnotes get corrupted or Word says
that "There are too many edits". Is there a way around it? A style
to choose from?
