I am having the same issue, as well. For me, it started happening when I converted to Office/Excel 2010. Any number formats that were "General"
get automatically converted to another format when saved (so far I've seen all changed to either "Accounting" or "Date". This happens to the ENTIRE workbook (all tabs). Very frustrating -- it has happened now in two entirely different spreadsheets.
