I did some futher investigating.... I came up with a very simple
program that had 1 master and 1 detail TwwiboQuery .
The master data has 4 columns that the detail will use in a
parameterized query. One of the columns in the master may contain ''
(blank) data, but never null.

When I compile and run the program in Delphi 2005, the detail data is
found correctly. When I run the program in Delphi 2007 the program
does not find the detail rows that have blanks in the Master.

Is there a setting I'm missing or what?

Thanks in advance
