Checked on 5.0 - 7.2 Steps: 1. Open LO Writer 2. Menu Form > Design Mode [on] 3. Menu Form > Text Box 4. Insert text box to page, disable Design Mode, enter text in Text Box 5. Save as DOC/DOCX/ODT files. 6. Open every saved file, change text in Text box, resave in same format 7. Reopen files and check. ODT contains new text, DOC/DOCX lost changes. If you check Text Box option after reopen doc/docx you will see old text as "Default text" and changes in Default text will be saved after save/reopen. But text editing in text box will lost every time. It seems something wrong and text saved as Default text, not as TextBox text.
