Description: I work in LibreOffice Writer at home and used never to have a problem saving docs as .docx and opening them at work in MS Office. Now they won't open and the doc appears in folders as having no extension, even when I put one in again manually. Pages can't read them either, though it will accept manually added extensions. Steps to Reproduce: 1.click 'save as' in a writer document 2.select .docx 3.close document 4.open document in MS=Word 5. MS-Word says it can't open extensionless files. 6. Manually add .docx to document name. 7. Click to open, but doesn't work. Actual Results: Document didn't open Expected Results: Document should have opened in MS-Word as a Word document. Reproducible: Always User Profile Reset: No Additional Info: Pages can open the document as a Pages document if I manually add the .docx extension.

Created attachment 137815 [details] Writer document This document displays in LibreOffice as 'Textedit' though I saved it as .docx. In MS Office it displays as 'File' and won't open.
It seems you have accidentally unticked the box "Automatically select filename extension" in the file saving dialog.
