An Excel file updated using Calc and saved as an XLS for years with Open Office / Libre Office 4.1.2 is corrupted when saved by Libre Office 4.2. Formulas in ‘totals’ cells are lost and my copious comments point to the wrong cells and cells that never had Comments. The saved XLS file can not be opened by Excel 2000.
Restored XLS file from backup and tried saving without modifications as an ODS file. Virtually all Comments are missing from the resulting save and many formulas in total cells are missing.
Will revert to previous version (4.1.2) until 4.2 is actually ready for prime time.
