Problem with Excel item type - can't save

[David_F]

Sorry, answering my own question here.

The solution was that I needed to added .zip to the file extensions in "File Extensions to Open Stored Documents Writeable". I already had it in the "Open in Browser" extensions, but not there.

I had no problem with opening/editing/saving .docx files, even without including .zip. I guess Word isn't so fussed about that aspect...
