I tried your demo. For me IVBFlexDataSource2_GetToolTipText fires always. Also at the end of the table.

Regarding the slowleness. If I comment out the code on IVBFlexDataSource_GetData in your cFlexDataSource then the grid is fast, always. So it must be something with the .record moving of the DAO db.
