It appears the problem is with MSQuery on a the Intel Macs. It is the samerealbasic program that is available for download from Microsoft Mac downloads. It's been around since the last office that worked on OS 9. It seems that since the application only works under Rosetta, it can't interact with Universal programs like ODBC connectors.
I was extremely disappointed to see that this very useful tool has not been upgraded to work Universally and has become useless. It has left us in a dilemma on how to do our SQL Queries with Excel.
While it's true that MS Query is not a Universal Binary, it works just
fine in Rosetta. It can certainly work with Universal Binary ODBC
drivers (it just uses the PowerPC fork of the UB instead of the Intel
fork).
MS Query is not as polished as the rest of MS Office, but it is
certainly adequate for creating queries.
