Would it help if form B use default DS?

>So I'm finally putting out my .exe in VFP9 (had been in VFP8) and have a bizarre bug relating to now you see it, now you don't data. This problem only shows up in the compiled .exe, not in the development environment.

>From Form A (no data buffering) I'm adding a record directly to a table (in a database) and then calling a modal form B to edit that record directly, without table buffering. Then, when the user closes Form B, the control returns to the calling form A. The data at this point is there, I can browse the table from VFP and it looks good and it is showing properly in a listbox on Form A. Then, when I close form A the data that was previously there, is now reverted back to the original default values (mostly empty). Again, this only happens in the .exe, not in development. Both forms use private DE's.
