I think I read that it's a real bug. You can change the Excel decimal
symbol to ".", open your file and change it back to ",".

I'm running Finnish language version of Excel. I'm importing a text file to
spreadsheet with several colums. Text file contains colums separated with
space. Some colums contain decimal numbers with "." (= dot) as separator.

When opening the text file in Excel some of the decimal numbers are shown as
dates and other numbers are formatted as general (not as a decimal number).
This is the result regardless of which decimal separator I choose. (The
default in the Finnish version is "," (= comma).

Old Excel handled this situation without any problem. So now I walk to an
other computer with Excel 2000 in order to able solve the problem. - Not
nice.
