Hey Dave,

This was, apparently my problem. I was not using the correct version of
the obdc driver for WinXP. As to the updateable cursors issue: The
only operation I am doing here is adding records to a table back on my
linux routine. Upon opening my CRecordset object I do not even retrieve
any records, simply supplying the table name where one would normally
insert a query to retrieve rows. Hence, I am hoping that I don't run
afoul of any of the problem areas for updateable cursors. Assuming I'm
naive about this, I would love a URL to which I can point my browser for
more information on this subject.

Thanks!
