I've never needed to use Open XML Converter, and keep updating it when prompted. But is this app no longer needed with Office 2011 now available? Since I no longer have Office 2004 or 2008 on my iMac, I doubt I'll ever see the files that XML Converter can convert. My only compatibility issues have been with reading XP Word files, but I can usually get around that. It's not that I need the 20MB of disk space the app uses, but if I can get rid of unused apps, I'm all for it . . . Thanks . . .
