I installed PDOX v9 w. ODBC under Wine and TCursors are working fine with
SQL Server v4.20. I updated my Win16 ODBC driver to Microsoft's latest Win16
v2.65 driver without any change, so it appears to be an issue with Paradox
v7 (latest Corel Win16) and its BDE v2.5.  

Too bad I couldn't get TCursors working w. Paradox v7 as most of my desktop
focus is now OS/2. I wonder if v7 ever had reliable support of TCursors w.
SQL databases? As a workaround, I'll see about running TCursor SQL batch
processing via Wine.   

Still enjoy wearing my Paradox Community "Paradox Day" sweatshirt :-)

Take care,

Sean
