Studio - Problem ODBC Connection

[Luiz Marcio Viana]

Hi,

I want to create a new data source from an odbc connection for access 
database, and I create the odbc system dsn and the datasource in the 
mapguide studio.

I tested the data source connection, and the test was successful. But, I 
can't use the "Refine Data Setup" to select the fields.

I'm using the most recently mapguide open source and studio files.

Has anyone an idea about what is happing?

Thanks
Luiz Marcio
