Subject Re: Fwd: Issues with Open XML in Office 2008 for Mac SP2
Date Thu, 30 Jul 2009 13:57:28 GMT
I've dropped a line on compatibility with MS Office 2008 on http://poi.apache.org/spreadsheet/index.html
This clearly describes the fix and how to remove it.

P.S. the .html will be available in a hour or two, after the next rsync cycle.
