Excel looses all file properties if containing many hyperlinks

[donatus]

Hi all,
I see the following strange Excel 2003 behavior:
- if the the number of hyperlinks exceeds certain limits, Excel 2003
Workbook looses all file properties (Title, Subject, ...), when I save, close
and reopen a Workbook.
- I experience this if the spreadsheet contains about 2'000 hyperlinks (and
a size of about 2 MB).

Any explanations?
Thank's
