Re: Office - open or closed?

In my experience (which admittedly ignores some features, for the sake of a simple life) that *is* what Office is doing.
In other words, *all* of the features you've used *are* supported when e.g. saving an ODF file and the message is just there to give your FUD a boost.
Having said that, sometimes it is necessary to generate an obviously less than capable format, such as RTF, to feed a particular process. In those cases it would be good if *all* of the wordprocessors would grey out the unsaveable options. That would save arguments and mean one doesn't need to beat writers into using WordPad (!) instead of their beloved wordprocessor.
