FMP12 and Excel XLS
I upgraded to Mountain Lion. I upgraded my Office to the newest version since Rosetta is no longer supported. When I tried to export a table to XLS format, from Filemaker Pro 12, it gave me an error message about Rosetta not being installed. Mountain Lion can run Libre Office and Open Office to open XLS, as well as generating an XLS to send to someone opening it on a Window machine with XP still. (Yes there are lots of office still running XP for compatibilty for the accounting software).
