Decimal separator not transferred correctly to polish Excel 2007 (54551)

Exporting data to a polish Excel 2007 on a polish Windows XP SP2.
The generated data containing the coma as a delimiter in decimal values, but when exporting them to excel there is a dot as the decimal delimiter. The setting is polish localization on windows that means the delimiter is coma ","
In TOAD " View | Toad Options ... | General | Numeric characters" are the correct settings "coma" for decimal.

WORKAROUND:
None

Waiting for a fix to be released in a future version of Toad for Oracle.
