Not personally but a lot of people here are using it either as a backend to
a MS-Access Active Data Project (ADP) or with a MDB or ACCDB Access database
file with ODBC Linked tables and/or passthrough queries with many versions
of Access: 97, 2000, 2002, 2003 and 2007.
Some gotchas here and there but with no fundamental problems that have not
been corrected since then.
