oracle linked server decimal problem

I'm attempting to query a linked server (Oracle) via QA. My query returns the expected record set, but the data for the decimal columns is not correct (only displays zeros to the right of the decimal point). My T-SQL:
SELECT amount
FROM oracle_src...budget
... yields the result:
..000
... whereas the equivalent query via MS Access yields
2784.56
The data type for the amount column in Oracle is defined as Numeric(9,3).
Any thoughts? I could pass the whole query process through MS Access to Oracle, but ... seems like there should be a more elegant solution. Thanks for any suggestions!

I may have found a work around for this problem. I was using Oracle's ODBC driver, version 8.01.05.00. I switched to using the Microsoft ODBC for Oracle driver, version 2.573.9030.00, and the problem seems to have resolved.
