Summary: MS Excel regression - can't save valid files
           Product: Wine
           Version: 20040615
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: wine-binary
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

With versions of wine up to and including Wine-20040309, I could get MS Excel
2000 could open, close and save files without incident.

Subsequent versions (20040408 onwards, including 20040615, which is currently
installed) still generate a file when you File->Save, however, the file is now
not a valid excel file and cannot be opened with Excel running under Wine, under
Windows or with OpenOffice. Excel reports "File format is not valid", while
OpenOffice just crashes.

Since there is no warning that the file is invalid, this results in data loss.

Example:

1.    Start excel

2.    File->Save, enter a filename

3.    Exit excel

4.    Restart excel

5.    File->Open, select file. "File format is invalid" message displayed.

I will upload an example (invalid) file as an attachment.
