Writer’s Save As option now (LO 3.6.0, Windows7) seemingly attaches a CSV extension for save as type “Text Encoded” where previous versions attached a TXT extension. Is this a bug?
At the moment there are two bug reports:
→ Bug 52451 - UI: FILESAVE as Text (encoded) should offer .txt as file type and name extension (v 3.6.0.2 rc)
→ Bug 53071 - writer has no more option to save as text file (v 3.6.0.4 release)
Fixed in LO 3.6.2.
